If you are planning to get into DSP from a practical point of view, then there are only two books to get - and this is one of them. DSP is a complex subject, and if you are not in an educational environment where you have easy access to teachers who can advise you, then you could easily be turned off by diving into a book such as Schafer and Oppenheim's recognized text book on the subject. I am a retired ex-academic with an interest in signal processing, and decided to get back into the field, which had developed considerably since I was involved in basic continuous signal processing, which than revolved around Fourier analysis and integrals. I researched the market thoroughly and ended up purchasing Steven Smith's excellent book "The Scientist and Engineer's Guide to Digital Signal Processing", which gives a conceptual view of DSP without getting too involved in the mathematics of the subject. Having worked through this book and established a solid basis of what DSP is all about, I decided that I needed a little more mathematical support to the concepts, and settled on the current book. What a good choice. These two books are a perfect complement to each other, and the writing style of the authors is very similar. Anybody getting into DSP is strongly advised to purchase them both. But back to the current book - this book focuses on the reader and makes you feel that you are interacting with a teacher rather than puzzling over equations. It leads you gently through the concepts, but doesn't bypass thorough considerations of the development, for instance, of the Fast Fourier Transform, which can be quite intimidating. This is a chapter that you can scan through without disrupting the rest of the material.

In every field there are books that just stand apart. They are so well written that they change your opinion about the subject. In fact, with most mathematical ideas if you understand them well, they no longer seem tedious, or hard. Richard Lyons book "Understanding Digital Signal Processing" is just such a book. I remember coming across it on when was young. This was before had a "look inside" feature and one was generally leery of ordering things on line. There was a introduction to the book written by the author which I read. The writing style was impressive and so I ordered the book. I still remember looking through and thinking this looks fun! It had more pictures than it had formulas! How often do you get excited looking at a textbook!I read the first chapter that night and felt exhilarated. I had my first aha moment in DSP. Although I was out of graduate school for several years at that time, I felt that I had never really understood the subject. Yes, I could do the transforms for homework etc., but understood, not really. In this book, Lyons starts with discrete signals, goes through sampling and aliasing in the first chapter. Each chapter build gently on the previous. All just a model of clarity and beauty. I particularly loved the filter chapter, with such easy to understand exposition of what the equation meant, the forward part and the reverse part. We all love pictures and the book's strength is its ability to communicate not just in words but also in figures. From DFT to filter design to DSP algorithms, all come alive as explained by Lyons.I think I did read the whole book in about a week. I had been writing papers and felt that this is the way engineering should be taught. This is the way engineering books should be written.
