Average Customer Rating:  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) 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 to start 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?!
the best book for scientist and engineers who use MATLAB to process time-series everyday This book is not a textbook, but it is far more useful than the popular text books on the topic of DSP. A lot of the concepts explained here really affect the effectiveness of common data processing programs. Highly recommended for anyone who use MATLAB and FFT on a regular basis. Intuitive and all-around excellent, but not for everyone I read this straight through, cover to cover. I have found Lyons's discussion to be illuminating and intuitive on a number of points, but this book is not for everyone.
Lyons doesn't major on long equations and proofs the way most DSP books do (e.g, he omits the actual algorithm for Remez exchange and suggests the reader use an existing implementation in his favorite software package instead). The math is simpler here because he is aiming for intuition and understanding, not algorithmic mastery or mathematical rigor. That can be a good thing, depending on what one wants out of a DSP book.
The single most helpful chapter compiles and updates the author's DSP Tips and Tricks columns from an IEEE DSP magazine. One trick therein (computing a 2N-length real FFT as an N-length complex FFT) found immediate application at my workplace and provided significant speed-up in our application -- even more than he predicted because of the optimizations in our FFT library. Even so, it seemed to me that most of these 30-odd tricks could have been incorporated into the relevant chapters, perhaps in a "Tips and Tricks" section at the end of each. It was a little awkward at times to have some trick for an algorithm discussed four chapters ago.
One of the least helpful chapters to me was on specialized FIR filters. It seemed (particularly first half on frequency-sampled filters) like a more advanced and optional topic than its placement in the book indicated, and after it, the discussion returned to more fundamental matters. I understand that the author wanted to put the filter design chapters together, but it seemed to me like a diversion from the main flow of the book into unnecessary complexity. If the chapter had appeared at the end of the book, it probably would have been better for me, and, according to an email, the author may remove it from the next edition. (Since you know now what I didn't know then, just skip that section until later if you prefer.)
The reader should look elsewhere if he wants problems to work out at the end of each chapter or if he seeks to grasp the deep theoretical details of signal processing. And I don't think this is a good book for introducing DSP to someone who has no schooling in or on-the-job experience with it because it assumes some background knowledge that the neophyte just wouldn't have. (My boss, who has a degree in mathematics and has been doing software engineering for 20 years or so, confirms this opinion from when he tried to read it. Now that he has more hands-on experience with DSP thanks to a project we've been on, it is more useful and comprehensible for him.)
But for a refresher or for getting some math and theory to back up real-world experience, it's a good place to look -- perhaps the best place. |  |
