Descriptions du produit

Quatrième de couverture

This is undoubtedly the most accessible book on digital signal processing (DSP) available to the beginner. Using intuitive explanations and well-chosen examples, this book gives you the tools to develop a fundamental understanding of DSP theory.

The author covers the essential mathematics by explaining the meaning and significance of the key DSP equations. Comprehensive in scope, and gentle in approach, the book will help you achieve a thorough grasp of the basics and move gradually to more sophisticated DSP concepts and applications.

The book begins with a complete explanation of the often misunderstood topic of periodic sampling. The introduction to the important discrete Fourier transform, and its fast Fourier transform (FFT) implementation, is the most lucid and illuminating explanation available anywhere. You will also find extensive information on both finite impulse response (FIR) and infinite impulse response (IIR) digital filters, as well as coverage of the benefits of signal averaging. In addition, the book demystifies the abstruse topics of the Convolution theorem and complex signals. The practical uses of various binary number formats are also carefully described and compared. Finally, a collection of tricks-of-the-trade used by professionals to make DSP algorithms more efficient will help you apply DSP concepts successfully.

Not Just Another Textbook! 26 août 2000
Par Brian Morse, 1LT, US Army Signal Corps - Publié sur
Format: Relié
I just received this book in the mail yesterday and haven't been able to put it down! This is the first review I have ever written but I wanted to express my thanks to the author for this book while also letting others know what a great resource it is.
This book is an excellent source for engineers seeking familiarity with DSP. I'm an Army officer trying to prepare for civilian employment in DSP design, and it has been over 4 years since I graduated with a degree in electrical engineering. Until opening this book I had no exposure to engineering since graduation, but I had no trouble understanding the material presented in this amazing book. Mr. Lyons says it all in the following quote from the preface:
"It's one thing to write equations, but it's another matter altogether to explain what those equations really mean from a practical standpoint, and that's the goal of this book."
This book is simply the best-written textbook I have ever encountered, in fact some fictional novels I have read are less engaging than this book! Mr. Lyons discusses very technical concepts clearly and fully, requiring only moderate effort on the part of the reader to fully grasp the material. He also includes occasional historical references or quotes that I found very entertaining, such as the origin of the word 'analog' as it relates to digital systems.
I took two basic courses in signal processing in college, basically manipulating formulas and drawing pictures with no real understanding of what was actually happening. In just two hours of studying Chapter 2, Periodic Sampling, I developed an intuitive understanding of sampling theory, lowpass and bandpass sampling. These topics were merely abstractions in my mind after intense study and several one-on-one sessions with my professor at a challenging technical college! Wonderfully intuitive yet thorough treatment of a complicated subject, Mr. Lyons.
A word of warning - this book is definitely intended for engineers. Treat it like a college course with a prerequisite of basic signal analysis and electrical systems knowledge, along with a working knowledge of engineering mathematics, and you can't go wrong.

The Best DSP book for beginner 24 février 2004
Par Julius Caesar - Publié sur
Format: Relié Achat vérifié
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!

Very good book...enlightens without dumbing down!!! 1 avril 1998
Par JSBachRules - Publié sur
Format: Relié Achat vérifié
I'm a grad student in EE, and have had half-a-dozen DSP classes over the years. Many questions have remained unanswered over this time and I'm happy to say that this book filled in the missing pieces. Judging from the topics Lyons chooses to elucidate, it is obvious that he has traveled this confusing road himself, emerging victorious on the other side of the tunnel. He graciously shares his hard-won information with the reader, shedding light on various ubiquitious DSP confusion causing topics (i.e. convolution, digital filter design methods, DFT/FFT, etc.) If you're a EE that needs to really acquire an intuitive feel for DSP, this book is the answer. He doesn't dumb down the subject, either. Although one can certainly delve deeper (many references are provided), Lyons does a good job of explaining and describing the math. He has a wonderful colloquial style that makes it seem like you're discussing this stuff with a buddy. I can't recommend this book high enough. It's worth several times the purchase price.

Great for learning the reasons behind 23 avril 2001
Par Tee C K - Publié sur
Format: Relié
I had taken a dsp subject during undergraduate course in engineering school. Our lecturer had recommended us a text by Oppenheim et al.- "Signals & Systems", and claimed that the book to be quite informative as introductory text. I don't question that book to be informative, but I doubt it to serve well as an introductory text. For most of us in the class, it definitely doesn't seem to fit as a beginner material, especially we didn't have previous background in signals & systems. If one thinks that, "mathematics" should not meant for understanding an explaination, then most probably he/she would feel difficult to read that book. Same thing go for most of the other signal processing books.
I've passed the dsp exam by gobbling up all the mathematics, but without success in understanding the truths (reasons) behind. Since then, whenever I saw any 'unexplainable' maths to 'explain' a signal process, mostly I would just being frightened away, or even stopped from continue reading it. This certainly couldn't satisfy my desire towards learning new knowledge.
Then, I decided to take a try on this book. Luckily I did. It is indeed the kind of stuff which should be taught in the first place, especially to students (or engineers) who want to learn dsp for the first time, without too much struggling.
This book is understandable, readable, & easy to swallow. Richard Lyons tries avoiding mathematics whenever possible, however if the maths is unavoidable, he will explain it in plain english by giving a "numerical + graphical" example to better visualize it. For example, instead of telling convolution is y(n)=h(k)*x(k), he would further depict the convolution, terms by terms, in the way of y(n) = (1/3) . x(n-2) + (1/3) . x(n-1) + (1/3) . x(n), and putting graphical explaination to aid in better understanding.
If you are looking for a book to start taking off from the land of DSP without prior knowledge on it, no doubt this is one of the best books available. If you are to understand the "reasons" behind dsp in simple way, after learning the maths, like me, this is for sure the first recommendation of all.
After finishing this book, I can't wait to go for other classical books, like the "discrete-time signal processing" by Oppenheim.

Excellent introduction to DSP 20 janvier 2001
Par Steve Uhlig - Publié sur
Format: Relié
Unlike many engineering books, this one explains all concepts without assuming you already master DSP ! It goes at a pace that allows you to follow the course of the chapters without forcing you to dive into many other books. However, it covers all the basics from DSP and even more advanced topics.
This is a must-read as an introduction on DSP. Books like Franklins et al.'s "Digital Control of Dynamic Systems" or Oppenheim's "Discrete Time Signal Processing" are not meant to be introductory textbooks...but once you'll be done with this one then you can go to the more advanced ones.
For another introductory book, the one from Proakis and Manolakis also deserves a mention, but Lyons's is my first choice for introduction. Lyons's style and presentation are better... I would recommend using Lyons for a first iuntroduction and then to Proakis and Manolakis for further mastering the subject, but staying at an introductory level...
