Book Description

For senior/graduate-level courses in Discrete-Time Signal Processing.

Discrete-Time Signal Processing, Third Edition is the definitive, authoritative book on DSP – ideal for those with introductory-level knowledge of signals and systems. Written by prominent DSP pioneers, it provides thorough treatment of the fundamental theorems and properties of discrete-time linear systems, filtering, sampling, and discrete-time Fourier Analysis. By focusing on the general and universal concepts in discrete-time signal processing, it remains vital and relevant to the new challenges arising in the field.

Customer Reviews

The American hardcover is outrageously expensive. Just buy the softcover international edition on abebooks.com or wherever you can find it. I paid ~$22. The content is the same. Some end of chapter problems are just shuffled around or they recycle 2nd edition problems.

As for the actual content, I rated 3/5 stars.

I don't think this book is as pedagogically sound as Oppenheim & Willsky. Like O&W, this text suffers from over-wordiness. Also, in later chapters, O&S write their text assuming you are very fluent with Z-transform, system functions. If you are not, this text will be frustrating to read.

The biggest gripe I have with this book is that important theorems and relations are buried in a wall of text. O&S does not do as good a job as O&W does on boxing and highlighting the essential concept of the section. For example, you would have to scrutinize the text very carefully to figure out that linear-phase FIR filters always have zeros that come in reciprocal pairs - it's only addressed in a small paragraph out of ~8 pages or so on linear-phase filters!

On the flip-side, there's a lot of valuable information in here. The only other DSP text I have read to compare this to is this:

This is a more practical and less mathematical text that may be a good complement to O&S.

I had to buy this article as mandatory textbook for a Digital Signal Processing graduate course. It is definitely a complete and deep treatment of digital signal processing. However, I found it a little bit difficult to read and this is why I used it mainly to try to understand those concepts that were not clear to me from the lectures/notes. So far, the book gave me all the answers I needed.
