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
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… Read more
