Essential !
It is not a reference book but it will help you understanding the core tools in DSP....great book!

Great DSP book with clear explanations
This is a great beginner's DSP book with clear explanations and is less math-heavy than other books in the field.It was recommended by a DSP-enthusiast friend who has read many books in the field.I'm using it to supplement the text for my graduate DSP course which is more a text for those who have previous knowledge ("Digital Signal Processing Using MATLAB" by Ingle and Proakis)

Perfect for begginers
Alright. This book is really very good for the beginners. It gives you a general idea about DSP. ItS beauty also coming from the small amount of using complex formulas. However you should be careful about a point. After finishing this book, do not expect to be an expert in DSP. You will have understood lots of small topics inside DSP after finishing this book. I strongly recommend you to continue with an higher level DSP book after Lyons' book.(like Proakis and Manolakis).When you read this book, you may surprised so that you can finish it in a couple of days due to its simplicity and attraction. Thanks for the writter so that I will start to read his second book, Streamlining DSP.

Best introductory book on this subject
This should be everyone's first DSP book - it's clear, motivating and by no means superficial. It takes you from crawling to walking and you won't even perceive that by the time you end it you are ready and willing tostart trying to run.

Actually it's quite surprising that no one apparently wrote about DSP's along the very logical, continuous - no jumps that will leave you asking how it got there - and intuitive line adopted by the author. In blunt words, if you can't learn basic DSP theory from this book then DSP is not something for you. Any other comments I would add, all positive, would be more of the same already expressed here by other readers.

Not useful for me at all!!!!
Unlike a lot of positive comments about this book, I found it terribly difficult to underestand! There are things that have been over explained (that bores you to death) and things that do not have any/little explanations (things that I always had problem underestanding them)! What sort of begginers book is this?!

Easy read
The book states quite clearly it's a graduate text.With this in mind, I feel safe in saying this book is a very easy read.The examples are easy to follow, and ideas/concepts are laid out quite well.

I'd recommend an intermediate background in mathematics (linear algebra, maybe as high as numerical analysis), and exposure to electronics would help in understanding the examples but isn't necessary.

Excellent theoretical discussion of DSP
This book provides a thorough theoretical background in DSP. It is an excellent reference book that covers every major topic in reasonable depth, without getting too academic. It is the only DSP book I've ever needed, and I have designed on several imaging and data collection systems.

My only reservation is that they apparently removed the discussion of state space in the newest edition, which is one of the most practical and common techniques in designing control systems. But you can always get that info online, and you can try it out in Matlab.

6 Stars book!!
Great explanation for every fundamental concepts. For instance, authors give a deep introduction about the background and purpose of Fourier Series and transform in Ch 4. The book demonstrates great details of Fourier Transform by constructing from mathematic components to a whole picture of Fourier Transform.
This textbook explains almost everything and provides much more details than the current textbook I am using in UCLA. I guess this textbook also much better than most textbooks, since most textbooks don't even bother to cover the real fundamental concepts.
However, as I reading along ch.4, there are many typo, but they all format problems so far. Ex. superscript, "x2" = x*x. integration from nothing to w, because it's lower limit become part of integral value.

But still, this is a great book without a doubt!!!

Things you will not easily find in other DC books.
This is the first book of Proakis I bought. The reason I didn't buy a book of Proakis since my second year in PhD was because I was traumatized by his Digital Communications book when I was a undergrad student. That book was so difficult for me to understant with it's complex equations and notations, I was virtually scared of Proakis. And the other reason was that what is discussed in his Digital Communications book could be found on other texts, explained much simpler with simple illustrations. So I did not have the need to get Proakis. But now, I wanted to learn about quantization effects of DFT/FFT, and there is not much references available. So finding it the table of contents I decided to buy the book. I was not really interested in the rest of the contents, since I already knew about them and had read atleast couple of other books regarding the same topics.
But I was in for a surprise. The book was not evil as I thought it would be. It was easier to understand. Although the part on DFT/FFT quantization noise was quite limited, I found a plethora of other material, which I thought I had read in other books under the same chapter heading, but which I had never knew. For example, the chapter on Spectrum estimation towards the end of the book was really helpful as it described manytechniques such as MUSIC. ESPRIT and other eigendecomposition based specturm estimation methods, which I did not find in any other DC related books I read. Bottom line, this book is gold if you are working the in the area of digital communications, but I would not refer to this book if I am an undergrad. This is more of graduate level book.

Great for learning and as a reference
I bought this because my undergraduate Digital Signal Processing(DSP) class did not have a required text, only poorly written notes handed down over the years, riddled with mistakes. I did some research and found this was required for the graduate level DSP class (DSP II), so I figured I'd save money by getting it now. In that context, it was worth every penny. Great examples, great depth on the material, and very exhaustive. Now keep in mind much of the material is still beyond my grasp, but the material that was in the scope of the class was invaluable. It was expected that I was bringing "the good book" to our homework sessions, and other people began to depend on it.

Now its written, in my opinion, more as a reference than a linear flow that a textbook that instructs usually is. However, I had no problem teaching myself from this book; I just had to skip around some. I received an 'A' in the class, and while I worked very hard for it, the book proved to be a necessity. In my work outside of academia, I've referenced on multiple occasions for material that I've yet to master.

One final note, a good friend recommended Lyon's text, and I was sad I invested in this book prior to hearing the rave reviews. I have personally NOT read Lyon's text, but I can say as a beginner student in DSP, this book was fantastic, and continues to hold its value. ... Read more

Wonderful Book
What I always look for in a Engineering, Math or Science Book is worked out examples. This Book gives worked out examples as well as supplementary examples for each chapter. So it works out well for me

Digital Edition Interface Is Unusable
Unfortunately the interface for the digital version of this book is very awkward.I purchased the paper version of the book, and has proved to be quite useful.Hopefully the technology behind the web interface for digital books that Amazon employs will improve soon, as this method of accessing reference books makes perfect sense.Currently, however, I would steer away anyone thinking of purchasing a digital book of this kind, who is intending to use the web interface.

DSP book review
This book is mostly composed of formulas and math. It gives little background information on the reasons/motivations for the formulas. I would not recommend this if you are new to digital signal processing.

Clean book just like new
The book came fast, was much cheaper than a new book, and its quality was practically new.

Great Companion
This text was recommended as a companion to Oppenheim's "Discrete Time Signal Processing" for a senior DSP filtering course.If your school is like mine, you sit in three hours of lecture a week, nodding and agreeing and feeling like DSP is straightforward and intuitive.Then you sit down to do your homework and wonder, "where did this come from?"Schaum's helps to bridge this gap with compartmentalized topics and numerous examples.The sections help you quickly ascertain how the notation translates and how thoroughly the topic is covered relative to the coursework.The examples help because, let's face it, it helps to see certain types of problems worked through from start to finish.There are many, many examples within the sections and at the end of the sections, worked through in minute detail.If you're into or studying DSP as a senior engineering student, if you're not the top dog in your class but still want to do well, if you learn from examples and from working through many problems that you're able to confirm, then this book is for you.If you're looking for a "solutions manual" type of book, if you want a "cliff notes" type companion, or if you don't understand lecture concepts at all, then this book won't help you much.It's not an introductory text, although it covers introductory concepts, in my opinion there's not enough background on the rudimentary DSP topics to truly qualify as introductory. ...

The father and mother of all DSP books
This book "DSP" from Oppenheim & Schafer (O&S) is to digital signal processing what Kernighan & Ritchie "The C Programming Language" is to programming: an indispensable classic.

I learned DSP back in 1982 with a bunch of photocopies of this book. Today I own two O&S copies: one hardcover (at home) and one paperback at work. I don't remember finding a mistake, or even a typo, in the book, which nevertheless never went beyond the first edition (the 3 sequels "Discrete-Time Signal Processing" from the same authors are already geared to "textbooks"...). Back in 1975 there were book reviewers (or cautious authors...) that made their best to eliminate the mistakes that plague many modern books.

One of my DSP teachers said that one senior guy had told him how to learn DSP by himself: read O&S, chapter by chapter, and do 10 random selected problems from each chapter. So he did and he has since then published several important papers on DSP... Recently I had to review, seriously, random discrete signal processing and power spectrum estimation: the most readable pieces on these matters which I found were, precisely, O&S chapters 8 and 11.

In the last years I'm teaching DSP at one University. I've already got a dozenDSP books, ancient and modern, but O&S is still the reference I recur the most. If you could cross "DSP" from O&S with Lyon's"Understanding Digital Signal Processing (2nd Edition)", you would get the perfect DSP book: on the one hand, Lyons' is too verbose and avoids somewhat mathematics (by choice), but provides perhaps the best explanations on DSP you can find; on the other hand, O&S provide rigorous equations and both deep and broad coverage of DSP foundations.

If you want really to understand DSP, have a decent Math training (average Calculus, Complex Variables, Fourier Analysis skills), the book from Oppenheim and Schafer is in the top of the list I would give you to learn DSP.

A brief table of contents (adapted): (1) Discrete-time Signals and Systems. (2) The Z-Transform. (3) The DFT. (4) Graphs and Matrix Representations of Digital Filters. (5) Digital Filter Design Techniques. (6) Computation of the DFT. (7) Discrete Hilbert Transforms. (8) Discrete Random Signals. (9) Finite Precision Effects. (10) Homomorphic Signal Processing. (11) Power Spectrum Estimation.

Not enough mathematical formulas
In dsp course we are using this book. The problem with this book is that it does not provide formulas for many dsp calculations. Thus, I need to find formula tables else where. Besides, there are not enough examples to further understandsings of the materials.

The Old Version of the DSP Bible
"Digital Signal Processing" by Oppenheim and Schafer was, until the publication of their revised book "Discrete-time Signal Processing", the best DSP reference book.

While I would notrecommend this book for self-study, I would recommend it as a referencetext for someone who has done or is doing a DSP course.

Be advised ---the new version, "Discrete-time Signal Processing", is moreup-to-date. ... Read more

Product Description
Presents the knowledge necessary for an appreciation of the wide scope of applications for discrete-time signal processing and a foundation for contributing to future developments in this technology. DLC: Signal processing--Mathematics.Amazon.com Review
This is the standard text for introductory advancedundergraduate and first-year graduate level courses in signalprocessing. The text gives a coherent and exhaustive treatment ofdiscrete-time linear systems, sampling, filtering and filter design,reconstruction, the discrete-time Fourier and z-transforms, Fourieranalysis of signals, the fast Fourier transform, and spectralestimation. The author develops the basic theory independently foreach of the transform domains and provides illustrative examplesthroughout to aid the reader. Discussions of applications in the areasof speech processing, consumer electronics, acoustics, radar,geophysical signal processing, and remote sensing help to place thetheory in context. The text assumes a background in advanced calculus,including an introduction to complex variables and a basic familiaritywith signals and linear systems theory. If you have this background,the book forms an up-to-date and self-contained introduction todiscrete-time signal processing that is appropriate for students andresearchers. Discrete-Time Signal Processing also includes anextensive bibliography. ... Read more

discreet-time signal processing
A decent book, but the seller sent the international paperback version which came in three volumes and was very low quality binding.

Ignorance of Elementary Network Theory
The authors apparently are ignorant of elementary theory of electrical and digital networks. In the 1975 edition, on page 223, and in the 1999 edition, on page 829 - quarter of a century later - they give the formula for the transfer function of a digital network with finitely many components as a rational function of a Jacobian elliptic function of the normalized frequency.
The authors - all of them Electrical Engineers - should know that the transfer function of a digital network or an analog network with lumped components is a rational function of the frequency, whereas a Jacobian elliptic function and any function derived from it by rational operations is a transcendental function.No wonder students are frustrated in the classroom.

First text
This is just an amazing book. Seriously you can get a better deal for your hard earn money then this book .There good amount of examples and exercises to keep DSP fanatics entertained.
After reading this book I would highly recommend reading
"The Fast Fourier Transform and it Application by E.Oran Brigham"

For The Advanced
This book is widely accepted as the standard graduate level text for Discrete Time Signal Processing. Personally I think it could use a bit of elaboration and the figures and graphs should be improved upon.

I must say that for the most part it is comprehensive and thorough in dealing with this subject matter. Some of the trickier nuances are lost in this treatment of the subject.

I would highly advise this book to anyone who has a firm and solid foundation in subjects such as DSP, communications and possibly transform mathmatics. I would not under any circumstance advise this book as a starting point!

Additionally, due to the nature and level of this material... I would suggest a study guide to accompany. Having been out of school for only four years I entered an online masters program... I am expected to teach myself from the book, I have found the study guide to be necessary.

Comprehensive book on DSP
This is a comprehensive book on DSP. It is perhaps too much for a student approaching DSP for the first time but it is a very useful text for advanced students. It is also a good reference on the subject. Beginners would do well to go through the elementary book Signal Processing First by one of the authors Schafer before tackling this book. ... Read more

Product Description

A practical and fascinating book on a topic at the forefront of communications technology. Field-Programmable Gate Arrays (FPGAs) are on the verge of revolutionizing digital signal processing. Novel FPGA families are replacing ASICs and PDSPs for front-end digital signal processing algorithms at an accelerating rate. The efficient implementation of these algorithms is the main goal of this book. It starts with an overview of today's FPGA technology, devices, and tools for designing state-of-the-art DSP systems. Each of the book’s chapter contains exercises. The VERILOG source code and a glossary are given in the appendices. The accompanying CD-ROM contains the examples in VHDL and Verilog code as well as the newest Altera "Baseline" software.

Necessary in your design or teaching task
Dr. Meyer-Baese covers very interesting signal processing topics using reconfigurable hardware (FPGAs) in this work.The book contains a good overview of FPGA technology and tools for implementing digital signal processing systems (DSP). Computer Arithmetic, Filter Design (FIR & IIR), Multirate Signal Processing, Fourier Transforms, Advanced Topics as Number Theoretic Transforms (NTTs), Error Control and Cryptography, Modulation are concepts very well exposed, finishing the book with a rigorous and complete chapter of Microprocessor Design that I teach at University. Every chapter has enough exercises perfectly thought to learn the basic and advanced concepts, which arevery useful for self-study proposal. Also VHDL, Verilog and assembler code is provided.
In short, a high grade choice as initiation or advanced reference in the field of signal processing systems in hardware.

Errata for the 3rd ed.please... it is indispensable
From among the many books on DSP I own, I've chosen the 3rd. ed. of Dr. Meyer-Baese "DSP with FPGA", more precisely ch. 8 on "Adaptive Filters", to be the base of a module on adaptive filtering belonging to a DSP course that I teach at a University. The reason behind the choice was that, at first sight, the chapter seemed to have a good balance of conciseness and range of adaptive techniques presented.
This means I read carefully ch. 8 and implemented in Scilab some of the adaptive algorithms. As a consequence, I also examined carefully the equations, mainly those on the Widrow-Hoff LMS and the RLS techniques.
What I found was several handful of mistakes. From the silly ones (the definition of variance in p. 481 is E{(x-av)^2} instead of E{x^2}, as the average 'av' is not assumed as zero) to errors in vectors transposition in the differentiation of matrix-vector products (e.g. in the gradient definition, in the middle of page 483, there should be x[n] x^T[n] instead of x^T[n] x[n]) which, sometimes, by miracle appear correct in the next equations, and ending in the mess with the use of [n+1] or [n] indexes in many equations in the derivation of RLS algorithms in pages 518-521, the lack of exactness in the theoretical derivations converts what could be a very good presentation/tutorial chapter on the AF topic in, at times, a messy bunch of equations plagued with mistakes.
The chapter on AF first appeared in the 2nd ed. of the book (2003). So there has been plenty of time to correct at least most of the mistakes for this 3rd ed. from 2007.
I also tried to found an errata, even that of the 1st ed. of the book which is promised in the preface, but I didn't succeed. That was a severe disappointment.
That said, I cannot agree with most of the Amazon customers which rate the book with 5 stars, and recommend the author to get some picky reviewers that can catch and correct those (and other I don't mention) nasty typos and mistakes. To the reader using the book I suggest him/her to consult, for instance, the books from Widrow & Stearns or Simon Haykin to obtain correct derivations of the fundamental equations behind the basic theory of AF.

Starry
Comes from the DSP hardware Stars. Actually the only book on DSP hardware design in the market as of 2007. So there isnt much of choice, if you are into this businees. Good value for money, a hefty, detailed treatment.

Barely connected with FPGA,Practical? No
I was so disappointed after I read the book. I had expected to get some practical examples about implementing DSP in FPGA.I regret I was attracted by the name of the book and some reviews definitely not from sillicon valley . Except in chapter1"introduction" there lists some basic FPGA concepts, I hardly say how this book was named as "DSP with FPGA".
It does provide lots of mathemetical models, graphs for each DSP component, I believe it will be much more helpful to writing a PhD thesis rather than using as reference book in industry.
If you are expecting to get some practical examples about implementing DSP in FPGA, this book might not be a choice.

Excellent for DSP Implementations
In this book Dr Meyer-Baese brings in his industrial/proffessional experience from the field of DSP using FPGAS. Lots of other FPGA/Hardware books just talk about the theoretical/concetual/abstract level DSP. Here the main focus is the practical implementation of the different DSP Components
everything from Multipliers to the Discrete Wavelet Trasform.
Each of these components are seperately discussed chapter-wise and is supplemented by applications and also source code in both VHDL and Verilog (mostly in the accompanying CD)
If you just want to know what an FFT is then this book is NOT for you,but if you want to implement this in hardware then this is THE book. ... Read more

Product Description
Signal Processing for Neuroscientists introduces analysis techniques primarily aimed at neuroscientists and biomedical engineering students with a reasonable but modest background in mathematics, physics, and computer programming. The focus of this text is on what can be considered the 'golden trio' in the signal processing field: averaging, Fourier analysis, and filtering. Techniques such as convolution, correlation, coherence, and wavelet analysis are considered in the context of time and frequency domain analysis. The whole spectrum of signal analysis is covered, ranging from data acquisition to data processing; and from the mathematical background of the analysis to the practical application of processing algorithms. Overall, the approach to the mathematics is informal with a focus on basic understanding of the methods and their interrelationships rather than detailed proofs or derivations. One of the principle goals is to provide the reader with the background required to understand the principles of commercially available analyses software, and to allow him/her to construct his/her own analysis tools in an environment such as MATLAB®.

· Multiple color illustrations are integrated in the text
· Includes an introduction to biomedical signals, noise characteristics, and recording techniques
· Basics and background for more advanced topics can be found in extensive notes and appendices ... Read more

Fills an important niche
This book is clearly not intended for the beginner. It is intended for graduate students or undergraduates with a good working knowledge of at least calculus although many people benefit from previous exposure to differential equations in reading this book. There are many books out there in the math and physics literature that cover many of these topics but are entirely incomprehensible to the average neuroscientist. This book is the only book on the market that bridges the knowledge gap between students who already possess an introductory quantitative background and those capable of reading modern quantitative literature from fields such as engineering and signal processing. It is also the only book for neuroscientists that introduces these more advanced concepts from the perspective of a neuroscience (i.e. using EEG recordings, etc. to illustrate the methodology). Finally, the Matlab code presented in the book can in many instances be used directly in one's own research making this book a very practical investment.

May be difficult for novices
As a new user to Matlab, I found this book too challenging to be effective.

Useful.
This book contains useful exercises and demonstrations of MATLAB code that are worth looking at.Overall, I think it covers the major topics and does a decent job fulfilling that purpose.

Having said that, however, the language of the book is not reader-friendly.It's not to say that we aren't dealing with advanced material here, because it wasn't intended for the beginner.Don't expect that you'll just be able to pick up the text and read it without any prior knowledge.

I would have given this book an additional star, however, there are some errors of calculation in the beginning exercises.If you are the advanced reader, you'll pick up on these--someone other than myself actually picked up on these, so don't just take the calculation and their end result to be the answer--as always, be cautious when you read. ...

Great book
The book was shipped and delivered very fast. It was in great condition, brand new. It was out of all my expectations. Thank you, AMAZON.com! I absolutely love this book!

Discrete-Time Signal Processing
Many figures, derivations, and concepts in this book are not thoroughly explained, making them difficult to follow.It is also sparse on good example problems.This book is obviously written for graduate students who already have a solid grasp of the basics of signal processing and higher level mathematics like Fourier transforms.If you don't have a solid grasp of these things when you start reading this book, then you are probably going to be very frustrated with it.

Great reference, but confusing for class
I am writing this as an electrical engineering student at Brown University, RI, USA.

My general comment for all textbooks by A. Oppenheim is:
His books are exhaustive, professional and can be great references for your entire engineering career. However, from the pure student perspective, Oppenheim's books are hard and confusing to read (in addition, the huge knowledge provided cannot be assimilated) for the purposes of a course.

The books covers several aspects of Digital Signal Processing (DSP) and it's considered the best of this kind. It contains what an signal processing electrical engineer needs for his job. There are many strict mathematical proofs which explain how the DSP concepts have been developed, but they make it really confusing to the student to understand the practical meaning of signal processing.
The book has many many problems ranging from basic to extremely complex ones! These are generally a pain and their solutions require much thinking and deep understanding of the concepts (simple studying of the book's theory material doesn't help). In the newest editions, I think that there is a Matlab guide accompanying the book or a similar online tool, which provides ideas for Matlab probles/projects.

As I said before, the book can be a great reference for a professional career and I definitely recommend it as such. It has been the 1st and most complete book of its kind describing the (fairly recent/new) concepts of DSP. However, be advised that it's hard to read for a semester-long class. Definitely, good notes provided by the Professor and/or help and support from TAs or Professor are imperative to enhance understanding in a DSP course and improve performance in exams etc. Real-life projects and applications are even better to work on in order to realize the full realm and potential of DSP.

The best textbook on the market concerning DSP
This is the outstanding 3rd edition of Oppenheim's classic DSP book, which for over two decades was the only real choice for a textbook on the subject. That was too bad, since the first edition was probably the worst thing I have ever seen in print - terse, incomprehensible, and with only a few awful and poorly illustrated examples. When I decided to take a refresher course in DSP in 2006, I was horrified to see our class would be using the second edition of that horrendous text. What I found instead was a completely rehabilitated textbook! This was not a beginner's DSP textbook by any stretch of the imagination, but absolutely everything is explained and there are plenty of well worked out examples. The end-of-chapter problems were broken down into simple, intermediate, and advanced problems with quite a few mind-puzzlers in the advanced section. Plus, the answers to the first 20 problems in every chapter were in the back of the book.
There is really nothing unique about the book's format. What does makes the book unique is the density and amount of material included. Just about every page is packed with well-explained important information. I highly recommend this book to anyone who has had a prior semester of an upper-level undergraduate class in Signals and Systems and wants to study DSP. An accompanying book that you might find helpful is "Understanding Digital Signal Processing" by Lyons. That book is good for getting an intuitive feel for DSP. Another book that will help you with some of the earlier concepts in this book (linear systems, DTFT, Z-transform, DFT, basic filter design) and some of the direct computations involved is "Schaum's Outline of Digital Signal Processing". Amazon does not show the table of contents, so I do that here:

1. Introduction
2. Discrete Time-Signals and Systems
3. The z-Transform
4. Sampling of Continuous-Time Signals
5. Transform Analysis of Linear Time-Invariant Systems
6. Structures for Discrete-Time Systems
7. Filter Design Techniques
8. The Discrete Fourier Transform
9. Computation of the Discrete Fourier Transform
10. Fourier Analysis of Signals Using the Discrete Fourier Transform
11. Parametric Signal Modeling **
12. Discrete Hilbert Transforms
13. Cepstrum Analysis and Homomorphic Deconvolution **

Appendix A. Random Signals
Appendix B. Continuous-Time Filters
Appendix C. Answers to Selected Basic Problems

There are two new chapters in this third edition which I have marked with double asterisks. Previously cepstrum analysis and homomorphic convolution were mentioned in the second editon, primarily as just more advanced problems at the end of a chapter. All other chapters in the book remain essentially unchanged.Thus this third edition seems to continue the tradition of the second edition and looks to be a worthy purchase and update. I heartily endorse it.

Good book, but it has a one-time on-line study card!!!
I purchased this book as a reference book, since I am perusing my Ph D in signal processing.To be honest, I haven't used this edition of the book yet, but since "Oppenheim and Schafer 2nd edition" was a excellent reference to learn digital signal processing, I expect this book to be as good if not better.Consult reviews of the Discrete-time signal processing 2nd edition to get a better understanding of how this book will be.

The real reason I am giving feedback is to warn potential buyers and resellers about the on-line study guide offered in this book.This is an attempt of the publishers to get instructors to require that students complete this on-line guide.By getting instructors to use the on-line guide, they will severely cripple the used-book market since purchasing on-line access to the guide material is 60 to 70 bucks.

Immense volume, meager quality
This is a very large book covering many areas of digital signal processing.I bought a used copy of the third edition to replace an earlier one. Unfortunately, many of the errors -conceptual, not typographical - have remained. For example, the authors state in Sec. 8.3 that the frequency response of an elliptic (Cauer) filter is a rational function of a Jacobian elliptic function of frequency.An electrical engineer would know that a transfer function of a network of discrete components is a rational function of frequency, whereas the Jacobian elliptic is a transcendental function.The typographical error in the name of the mathematician Schur has finally been corrected attesting to the fact that neither author ever read the original paper.The presentation is extremely detailed in trivialities, with as many pictures, including a derivation of the sum of a geometric series as an exercise, a subject usually taught in high school.Finally, as another example, the solution's manual gives the wrong answer for Problem 2.9(a) stating, in effect, that a periodic function possesses a limit as its argument tends to infinity, showing complete ignorance of the notion of limit by the authors.Books such as this have little educational value, confusing the student with tons of irrelevant information, non-standard nomenclature - the Cauchy Residue Theorem in Sec. 3.1.2 is renamed to Cauchy Integral Theorem - and wrong answers.This book, if properly corrected, would be very useful.

Excellet handbook for system identification background
It's very very useful book for system identification specially newstarted, because of the fact that system identification is heavily related DFT, FFT, Spectral Analysis, Wiener-Khinchine relations and so on. Congratulations !!!

A great theoretical introduction to DSP
This book is a great theoretical introduction to DSP. Although its size looks intimidating and there is a lot of math, this book is very good for a beginner because firstly, the size of the book is due to numerous examples as well as clear and detailed explanations for most of the concepts and secondly, it is possible to skip over much of the math if you are so inclined and take away the gist of the section. This is the case in some of the more advanced topics covered which may be suitable for a second reading.

Some of the things I liked in this book are:
- The organization of the material and lucidity of the writing and explanation
- Consistency of notation
- The concepts of frequency in continuous and discrete time signals in Chapter 1
- The long introduction to discrete time systems and the concepts of linear time invariance in Chapter 2
- The explanation of Fourier series and Fourier transforms of continuous time and discrete time signals (periodic and non periodic) in Chapter 4 is the best part of this book
- Frequency domain characteristics of LTI systems in Chapter 4
- The way the DFT was introduced and its relationship with the DTFT in Chapter 5
- Sampling and reconstruction of signals in Chapter 9

Some of the things I did not like in this book are:
- The way the sampling theorem was derived in Chapter 4. In DSP you can derive the same thing in many ways but in many cases one method is more intuitive and simpler than the rest. There is an easier way to derive the sampling theorem
- There are mistakes in some equations. Not a major issue though
- There is no MATLAB or computer exercises or examples anywhere. This is a pity because you can learn so much and get a lot of insights with a few hours of DSP with MATLAB. Also there are some things like filter design which are done only on a computer
- I did not like the treatment of Multirate DSP in Chapter 10
- There is no treatment of 2D processing anywhere

On the whole this is a great theoretical introduction to DSP with a few minor drawbacks. I would still recommend this book over the ones by Oppenheim and Mitra for a beginner. But I would wait for the fourth edition that comes out in Feb. 2006 before buying any DSP book.

Something is missing ...
This book was required for a graduate-level DSP course, but I found it quite insufficient for study without a VERY good set of classroom notes.There are mistakes in various equations throughout the text, little to no examples, and I have yet to find a solutions manual.

The one nice thing I can say about the text is that it is thorough in its coverage.The book covers almost every topic I can think of for both undergraduate and graduate-level courses.My course has supplemented the text with "Discrete-Time Signal Processing" by Oppenheim and Schafer as well as "Adaptive Filter Theory" by Haykin.I found Oppenheim's text to be better for the examples -- even buying the Shaum's Outline for DSP can suffice.Haykin's text is for our coverage of adaptive filter theory.

If you're looking for a good undergraduate text try B.P. Lathi's book "Signal Processing and Linear Systems" -- it's much better and has been used at my University for a number of years now to teach our two undergraduate-level DSP courses.

Solid Book
I am a graduate student at USC and this book I actually used in lieu of the assigned book Digital Signal Processing (by Mitra). I referred to this book mainly because the assigned book hardly had any intuitive explanations and was quite convoluted. Proakis did a much better job in terms of the relationships between the various Fourier Transforms without comprising mathematical rigor. I also have Lyons Understanding Digital Signal Processing which is great for people new to DSP but I felt it lacked some depth in certain areas and did not have sample problems. Overall Proakis does a solid job with this book. I'd recommend it after knowing the material in Lyon's book. ... Read more

Summary of the DSP theory!
Best for study-a-night-before-test students. A 5 stars book for those kindof students. Theories were written with very short explanations, avoidingconfusing details, which give well understanding (though not deep). Iconsider the filter section is the best; after you read this section, youare able to know and design various kind of filter in a very short time ofreading. ... Read more

Digital Signal Processing: A Computer Based Approach
I purchased this book in Amazon marketplace. The book arrived in a few days, as expected. The quality of the product was identical to that specified in the Amazon site. I am happy with this transaction.

Interesting Book for DSP apps
Used this book for an intro to DSP course. Fairly high level for someone who is not interested in DSP applications or new to the field. Helpful in understanding applications of DSP.

review of purchased book
the book was in good shape at a good price, recieved a few days late.

digital signal processing
The text came in time for class to begin even though the time was short.

Great practical resource
I can't say how this would be as an intro to signal processing, but it's an excellent book for the working engineer. This one spends more time on top of my desk than any of my other textbooks. It includes lots of examples, illustrations, Matlab code, review materials, etc. And Mitra is the king of allpass filters! ... Read more

Outstanding DSP book.
This book helped me to implement the theory behind DSP. This is a perfect book that you can learn by doing.

The worst book on the subject
If you want to learn DSP. I suggest Oppenheim or Proakis.
I bought this book and after going through it for a few weeks had to throw it away!. Lacks mathematical clarity. Looks more like a cook book to me !.
Don't waste your money!.

This book is only OK
This book is OK. Its not a very good book as an introduction in my opinion. If you are a new student to DSP I would steer clear of this book and get Oppenheim & Schafer or Proakis & Manolakis first. However, if you are looking for practical coding examples for things, this book is VERY good in that regard. It could be useful to the new student as an alternate reference.

Content not up to expectations.
The book covers a broad subject area in adequate detail.However, it is riddled with typos, errors in equations, switched variable names and other "erroneous permutations".It forces the reader to really grind through the examples with caution.There are many "leaps of faith" in the examples forcing the reader to digress into research mode to fill in the blanks.Overall, the book does a decent job of explaining DSP basics.

Wonderful Book!
I am a postgraduate in University of Plymouth and fortunately enough was taught by Prof, Efeachor himself. His book is without doubt one of the most practical orientated DSP book, the writtings are concise, terse and vivid. His explaination style is impeccable, Anyway, Prof. Effeachor decades of experience in telecommunication, audio and medical electronics speaks for himself. Grab this book if you want to learn the real magic behind DSP.

One catch, there are too many typos in the book. Otherwise I would rate it 5 stars. ... Read more

This book was a horrible idea.
This concept behind this book is to introduce students to one of the more difficult aspects of ECE before they have even started the curriculum. I'm not sure how it is implemented at other colleges but at my college it is very much like a line from the original Willy Wonka movie:

"I've just decided to switch our Friday schedule to Monday, which means that the test we take each Friday on what we learned during the week will now take place on Monday before we've learned it. But since today is Tuesday, it doesn't matter in the slightest. Pencils ready!"

In short, this book CANNOT, by itself, teach you what you need to know. It is far too truncated and assumes you already know things you might well not. Furthermore, if the book is implemented as it is intended, the student isn't ready for the material contained in the book. On top of that, a critical component of the book is the Matlab portion. Which presumably some college integrate into an actual lab portion of the class. My college does not, and if you were trying to learn it by yourself..well obviously you wouldn't have a TA helping you. So, without a lab, you are at a complete loss for doing a critical part of the book...unless of course you already know Matlab.

This book is terrible, its implementation (at least at my college) is beyond terrible, and I can't imagine anyone using it to self teach without SEVERAL other textbooks to assist.

B.T.W. I'm sure professors, grad students, and people who already have a firm grasp of the all the unstated prerequisites for this book absolutely love the book. It seems like an advanced Schaum's outline pretending to be an introductory text...absolutely amazingly horrid, I hate it! and you should too!

OH and, as another reviewer pointed out. This book is NOT the same as DSP First: A Multimedia Approach, which I have not used and can't say anything about.

exellent condition
The product was quickly delivered in great condition. Had used sticker on it, but otherwise appeared new

Outstanding!
I have been using this book for my master's course and this is the first time I have understood DSP. And it feels great to finally have grasped the fundamentals of the subject that has long evaded me. The treatment in this book is very unique and novel. And the mathematics is used as a tool to help understanding the concepts and not given in the form of pages of proofs in which the reader can get lost. I salute authors for coming out with such an original and easy-to-understand approach to the subject.
Highly recommended!

Book CD and supporting web page is first rate
My only complaint is that some of the algebra should be worked out with a few more intermediate steps.The worked out homework problems are fabulous and sooo plentiful.

I wish I had the time to really read the whole book.My ECE201 course will probably only cover around 6 chapters.

Great Book
I think this book is absolutely outstanding. I don't understand any of the negative comments. The cd that comes with the book is indispensble. It provides example after example. I actually bought schaum's outline of dsp as well, but because of all the examples on the cd (they are handwritten) I don't even have a need to refer to the outline.

In addition, I thought the content of the chapters to be very readable. The only downside is that because the book is dated 1998 the matlab code is out of date and some of the drills no longer work with the newer versions. ... Read more

The Best book
This is the best book to understand the statistical digital signal processing, in a clear step-by-step mode.
It should be the first book to read on the matter.
Thank you Prof. Hayes, you wrote a great book.

Very good book
Very clear in concept and derivation. The excises following each chapter are also very helpful.

Excellent book
I took adaptive signal processing at Georgia Tech with Dr. Hayers. This book was used as reference for the class. I really enjoyed reading it. It is concise, to the point, with lots of example and matlab source code which acctually worked. I had learned a lot. More importantly I was able to put into practise during my 9 years industry experience after graduation. Good reference book, I recommend to everyone who is serious about this topic.

This is an excellent book for advanced DSP topics
This book has great material on least squares filtering and spectral estimation techniques. And with Hayes providing the Matlab code to implement the formulas, it is a great help to the student in being able to run the code and see what the outputs should look like. The book reads well and is very easy to use. But it is not a substitute for an intro DSP book like Oppenheim/Schafer or Proakis.

Update - I have changed my score from 4 to 5. The longer I have been working to more I find I use this book and the examples in it to do things. I think this is a really useful book for a practicing engineer.

Clear, concise, and clean
This book very clearly explains advanced topics in DSP. The notation is consistent and very clean, as well as the book layout and the writing. The examples are useful and the review section is very helpful. This is how a technical book should be written. ... Read more

Buy this for firewood only
Worst written book I have used in any of my EE courses. I am a graduating senior and intend on spending the rest of my life finding this author. This is a prime display of an author trying to show how smart he is. You are only smart if you can teach someone else what you know. No solution manual makes double checking your answers impossible.

Worst required text I have ever had
Lousy and sad for a 2nd edition.Examples are few and far between despite other reviewer's comments.Our professor has been kind enough to keep a log of the errors students have identified. There is a solutions manual for this but many of the answers contain errors as well.The only purpose for choosing this book is it covers both Continuous and Discrete analysis.This book will not even be a good reference later so hopefully I can find someone to take it off my hands.

Lousy Text
This is the worst text book that I've used in any course. As a physics senior, I suspected the material in an introductory EE course to be pretty straightforward, which it is. Ambaradar sure doesn't make it that way. With few worked examples, terse explanations and no odd-answered problems Ambaradar makes self-checking and learning almost impossible. Not recommended.

The Best of the DSP Books
I've looked at most of the DSP texts and personally find Ambardar's (2nd edition) textbook about the best.It will train you to use DSP as a tool, both in pen and paper analysis and in practice (e.g., using MATLAB). Some books will only make you a philosopher of DSP, this one will help you master the skills so you can actually do DSP.

Somehow Ambardar manages to discuss and provide examples on nearly every topic of interest to DSP with the exception of the very latest (see below).The sections are brief and to the point with many worked examples.The problems at the end of the chapter are actually do-able without having a Ph.D! Graphical approaches and shortcuts enrich the presentation and make the text fun to read.

On the downside, multirate signal processing is briefly explored and wavelets are only mentioned.Perhaps these topics will be enlarged upon in a future edition.

Excellent student oriented text
The author walks you through the material one small step at at a time.This text is as close to painless learning as learning wil ever get (if I may be forgiven a colloquilism).You don't need answers in the back because he works several examples for you on every page.
If I ever had to teach this I would use this book. ... Read more

Great Overview
This book does a wonderful job explaining the basic concepts and applications of digital signal process, without getting mired the details. The first half is really the primer,and the 2nd half explains the application of the concepts to the various fields of use. I can't imagine how this complex information could be conveyed any more simply. Kudos to Mr. Parker! I'm buying another batch of these books to help our non-engineering staff (sales, marketing, admin, manufacturing) better understand this critical (and now fundamental) technology.

a good overview
I purchased this book to help get me to a level where I could implement understand FFT's at a fundamental level and also help me to figure out a methodology to measure Doppler shift. In both respects the book was a definite asset.

The author has made a conscientious effort to provide good examples of various issues. Unlike some math books I'm sure we've all experienced, he does not lead you down a logical path in a solution only to leave you with "...the rest should be obvious...".

However (here comes the other shoe), DSP is a VAST and complicated subject. There is no way 260 pages can cover the subject enough to bring a novice such as myself up to the level of understanding most of it. I have been downloading/reading everything I could find on FFT's on the web. I found this book good to fill in the gaps in my ignorance on FFT's. I tried to read some of the other chapters as well for background info. I found that you have to have some background info/experience to understand some of the chapters. Chapter 5, for instance, is titled "Finite Infinite Response Filters". My background is hardware in general and I have done a little work with standard op-amp active filters. I read through the chapter twice and still have little idea what it's saying. The author seems to assume the reader has heard of FIR's before.

All in all, I like the author's style. It's informal and seems to flow in a logical manner with a lot of well laid out examples as to what he's saying. I wish he (or someone) would write a book twice this size, and narrow the subject field somewhat. For me it was worth the money. If you want to get introduced to DSP this is a good place to start. ... Read more

Product Description
This supplement to any standard DSP text is one of the first books to successfully integrate the use of MATLAB? in the study of DSP concepts. In this book, MATLAB? is used as a computing tool to explore traditional DSP topics, and solve problems to gain insight. This greatly expands the range and complexity of problems that students can effectively study in the course. Since DSP applications are primarily algorithms implemented on a DSP processor or software, a fair amount of programming is required. Using interactive software such as MATLAB? makes it possible to place more emphasis on learning new and difficult concepts than on programming algorithms. Interesting practical examples are discussed and useful problems are explored. This updated second edition includes new homework problems and revises the scripts in the book, available functions, and m-files to MATLAB? V7. ... Read more

Good MATLAB examples, high learning curve
I'm 6 weeks into a graduate course on DSP with this book.This is not a good intro to DSP book.It is a book focused on some previous knowledge of DSP and progressing on to use MATLAB to evaluate the subject.The problem is that the MATLAB examples are good, but theory examples are not varied enough and do not line up well with the homework problems, i.e. you will often be very hard pressed to apply the examples to the homework.

A good intro to DSP with MATLAB
This Book is a Good Introduction to MATLAB based DSP.To round out one's introduction, I also recommend Lyons' book on DSP as a companion.If one does not have MATLAB at home there are a couple of open source options that will work with this book.I chose SciCosLab GTK, but Octave from SourceForge also will work.SciCosLab GTK lets one do many of the exercises from the publishers website with little or no modification.

Frustrating
I have an expensive version of Matlab with the DSP toolkit. I was excited to learn how to use it from this book. What a let down. The first functions that I found were unusable making the examples worthless. Then I noticed a web site where I could download these functions that were created by the author(sited in the text): the link no longer exists (surprise!) rendering this book worth less than the paper it was printed on! Besides the link to the non-existent site the author gives no more incite into how to enable Matlab to work with this text. Don't buy this book!

Perfect but aging companion to Discrete Time Signal Processing
This book does exactly what it purports to do - it teaches the reader how to perform signal processing tasks using Matlab. It starts out with signals and systems and moves on to the DTFT, the Z Transform, the DFT, digital filter structures including both IIR and FIR design, and finally covers some advanced topics in adaptive signal processing and communications. It even contains full-blown projects using Matlab on adaptive channel equalization, binary spread spectrum communications, and system identification. The reader should use another text such as Oppenheim's "Discrete Time Signal Processing" to get the theory, and come to this book on how to implement that theory in Matlab. The one drawback is that the book is older, so it is using Matlab 5. Also, another reviewer mentioned that much of the book is inaccessible to users who do not have the rather expensive signal processing toolkit at their disposal. Fortunately, thanks to the open source movement, this last problem has been solved. Octave, now on SourceForge, an open source code repository, has many of the matlab functions available for free that you need to do signal processing.
In conclusion, I highly recommend this book to signal processing students and professionals who wish to incorporate Matlab into their work.

Excellent for review of DSP Mathematics....
Great companion book to "Understanding Digital Signal Processors" by Lyons and "Digital Signal Processors" by Hayes. I would recommend this book strictly for a companion book. It doesn't go into in-depth detail or explanation of Laplace, z-transforms, or Fourier Transforms but displays a good foundation for MatLab DSP routines. ... Read more
