Summary: This is how a textbook should be written!
Review: As an "over 40s" practising software/communications/dsp engineer coming from a dynamic control system environment I found the book very useful. It gives an easy-to-read description of dsp basics plus some handy tips and current practices. A must for system and specialist engineers in related fields (eg dynamic control systems, software, simulation, data analysis, rf and communications). Contains many detailed numerical solutions of equations. State space models and Z-transform transfer equations could maybe have been used to simplify notation, formulas and examples, but that would made it less readable for readers not so mathematically inclined. No mention of the effects of noise and clock accuracy. All in all, an excellent and user friendly book with a gradual but definite learning curve. Highly recommended to rusted practising engineers and students alike.

Summary: The Best DSP book for beginner
Review: Have you ever tried to study DSP but get intimidated with all the math equations and cryptic explanations?! With Lyons' book, you are not going to have these problems. Lyons' beautifully explains DSP "concept" without going to unnecessary mathematical details. There is still a lot of math in this book, but all of them is presented from practical point of view and only when needed. It teaches you enough basic DSP so when you need to learn advanced DSP concept from other books, you won't be intimidated!

Summary: Different approach
Review: I am a software designer and only interested in how to use the FFT, FIR or IIR to achieve DSP on telephony devices. To me, give me a sub-routine and parameters, all I need to know is how to effectively and correctly use it. This book not only tells me what kind of the parameters might be for these sub-routines and but also the inside of these techniques plus the interrelations among various factors. This book combined with Steven W. Smith's FREE digital signal processing book (online free at http://www.dspguide.com) would allow computer professionals with no previous DSP knowledge quickly get ready for the basic DSP techniques.Highly recommended! Excellent book for bed time reading! If you only want to buy one book, buy this and download the other free book. You are ready to go!! BTW, Can anybody send me the errata for this book? (Email: l_ting@hotmail.com) I found the equation 4-22, 4-23, 4-24 seems not quite correct, am I wrong or the book is wrong? Thanks in advance.

Summary: A must-read ! The title truly says it like it is!
Review: I ran into a copy of Lyon's text in the library, and on reading a chapter, decided to get my very own copy of this classic! As a student just starting to learn about DSP in electrical engineering, I found myself puzzled by vague explanations of aliasing and basic fundamentals of signals. Very clearly and masterfully, the author describes the key concepts, and unravels the mysteries with great expertise. The struggle and confusion is entirely done away with, and one gets the idea very quickly. I am still reading the book, and my copy is on its way! This book is a gem, and I will add it as a rare treasure to my library of technical books. I hope Lyons will write more books in the various other topics in EE. I'd definitely be very interested in them. In fact, I think I'll add TRW to my list of companies to apply to, when I graduate!Saroj Bon

Summary: One of the best technical books I've read
Review: I'll agree with the other glowing reviews here. This is one of the finest technical books I've ever read. It does a really great job of explaining concepts like the FFT so you can really understand them. A great introduction!

Summary: Great introductory text on DSP
Review: I'm and EE who's never had any classes in DSP. I'm now working in marketing in the telecommunications field and interface with engineers who work with DSP. I wanted to gain a better understanding of DSP so that I could better communicate with the DSP engineers and do a better job of proposing new concepts for products. This book did the job. Lyons really takes you into and through digital signal processing, including sampling theory, Fourier transforms and filters. If you're looking to really understand DSP, not so much from a mathematical point of view, but from a conceptual point of view, this book is excellent. The book is not elementary, however. You need the knowledge normally gained from aquiring a degree in electrical engineering to really grasp the concepts. In a way, that's a shame because only a limited set of people will get to enjoy Lyons really excellent writing!

Summary: Fantastic Book
Review: OK, let me first start out by saying that I am a little biased here since I helped review the new edition, but this is a fantastic book. While this book isn't a total replacement for the standard DSP tomes like Oppenheim and Schafer, this is a text that all DSP engineers should own. The second edition expands on the strong points of the first. The book is written by an engineer for other engineers. The topics are accessible to readers, while not being watered down. Less understood, but extremely important topics such as quadrature processing and Hilbert transforms have expanded coverage in this edition. The best improvement to this edition is the vastly expanded chapter on DSP Tricks. The tricks are practical applications of DSP theory. These tricks usually are not taught in school, and are often not well known. The number of pages devoted to tricks has doubled to over 100, and unlike other books, cover a broad range of topics. Application areas cover audio processing, digital communications, simulation, analysis, and others. In summary, you will not be disappointed with this book.

Summary: Wonderful Book for the DSP Beginner
Review: Rick's book sails the high sea of DSP books and stands out as a classic, in my opinion. Rick's excellent down-to-earth teaching style is mirrored in this book with his written explanation of DSP theory. A problem many authors have is that of skimming over detailed explanations using "clearly", "it can be shown", or "It is left to the reader as an exercise" instead thus leaving the student frustrated. Not Rick. Rick takes the time to guide the reader through numerical exercises in great detail leaving the reader with a sense of accomplishment. A particularly interesting topic that is covered in this book lacking in detail in others is that of band limiting (over sampling) DSP theory with good diagrams. I personally used Rick's book to come up to speed in DSP adaptive disk drive read channel VLSI IC testing techniques with great results. The typical DSP topics are covered (sampling, DFT, filters) without graduate level math. Rick covers single side-band modulation; a topic I found handy in HAM radio. But wait! There's more! The second edition of this book improves upon the first. Finally, note that the book does require that you understand calculus (integration, summation, and other typical higher level math skills) but at the level of a college senior. If you have the fortunate opportunity to attend one of Rick's classes, or meet Rick at a conference, tell him Dave sent you. Rick's book is an asset to any serious DSP student's library.

Summary: Excellent intoduction to the topic
Review: This book provides excellent introduction to the field of DSP. All major concepts are explained in simple, effective language. Also, the book features a lot of examples that are worked out _completely_. This will be of especial benefit to people with not-so-strong math background.
The author manages to make the subject not only exciting and easy to understand, but also fun to read, with small humorous snippets.
Highly recommended to anyone starting out with DSP!
