I have been using this book for my master's course and this is the first time I have understood DSP. And it feels great to finally have grasped the fundamentals of the subject that has long evaded me. The treatment in this book is very unique and novel. And the mathematics is used as a tool to help understanding the concepts and not given in the form of pages of proofs in which the reader can get lost. I salute authors for coming out with such an original and easy-to-understand approach to the subject.
Highly recommended!

My only complaint is that some of the algebra should be worked out with a few more intermediate steps. The worked out homework problems are fabulous and sooo plentiful.

I wish I had the time to really read the whole book. My ECE201 course will probably only cover around 6 chapters.

This book, along with "Understanding Digital Signal Processing" and Steiglitz' "DSP Primer" are the best, most useful, yet gentle introductions to DSP I have ever read. If only I had this book before I entered grad school! The CD-ROM that comes with it is very well done; a brilliant presentation! Highly recommended.
