Query: The reference for DSP

This is probably the most complete reference in DSP. It's full of examples covering the whole stuff in DSP. However this is certainly not fur use as an introductory book because the aim is not the explanation of fundamental concepts in DSP (for that go to Lyons "Understanding Digital Signal Processing"). Maybe it is possible to learn DSP with this book but then as a companion of a good undergrad course, not for self-study.As stated by another reviewer, this book is over-crowded with developments, details and examples that could be overwhelming to the newcomer. This is probably its biggest drawback, in that its completeness hinders on its readability. So be aware that this is not an easy DSP book, it's THE DSP book.
