Ok beginners book
This book seems to follow the disappointing (to me at least) model of many engineering texts--that being the reluctance to present new mathematical concepts/techniques. Almost every mathematical concept/technique used in this book was already covered by the prerequisite text by Oppenheim, "Signals and Systems." It would seem that a subject so entrenched with complex numbers and polynomials could be taught in such a manner that would include theorems and concepts from these well-established mathematical disciplines. Note that I did not read the chapter on Hilbert transforms, or the section on the Discrete Cosine Transform, so I cannot comment on them. I did read all other sections. The sections on random signals do introduce new concepts, but they were only put in as a quick review of concepts meant to be studied in a random processes class. On the other hand, this is a very readable book, which has proven very useful. It does present MANY new engineering concepts. If analytic function theory had been introduced, this book probably would not have been as complete a reference for existing introductory DSP theory. However by avoiding the math it has limited the continuing students ability to develop insight into deeper theory, or develop new theory.

On the difference between 2nd Edition and 1st Edition
I used the author's book "Digital Signal Processing" in my college study, and I also read and cite the 1st Edition of
"Discrete-Time Signal Processing" during my work experience. That's a very good reference. But I don't have the
2nd Edititon. However, after going through the Table Of Contents of the 2nd Edition of "Discrete-Time Signal Processing", I
think Oppenheim&Schafer did a resaonable tradeoff to reflect state of the art in DSP domain. They add: Discrete Cosine Transform (DCT) which is mostly used in image compression, Multirate Signal
Processing which is used widely in modern DSP, and Oversampling and Noise Shaping Sampling for A/D and D/A
conversion. In consequence, they remove: Lattice Structure, IIR Filters Design, Cepstrum Analysis (often used in speech
signal processing) and Homomorphic Signal Processing, which are a bit sophisticated. And I guess the reason to
remove IIR Filter Dsign is there exists many computer-aided tools on digital filter design, and made this very easy.

Very good reference
This book has its share of shortcomings, but overall, it is probably the best and most complete reference on DSP. Unfortunately, it does skip a few important topics. For example, the second edition threw out the section on designing IIR bandpass and highpass filters from lowpass prototypes. This section used to be in the first edition and is VERY important, so I don't see how Oppenheim & Schafer could have justified throwing it out. They also conspicuously left out filter design based on the frequency sampling method. But in spite of these omissions, it's hard to recommend another book over this one. The one that comes closest is Mitra's.In the end, if you want to learn DSP and work in the field, you have to have this book, as well as the ones by Mitra, Proakis & Manolakis, Jackson, and, of course, Rabiner & Gold. If you get all those, you'll have the complete reference of CORE DSP texts.
