Good Supplement to Oppenheim or Proakis (DSP book)
on July 27, 2003
This book is intended to serve as a supplement for an EE DSP course, which probably uses one of the texts listed above. If you want to self-study DSP I recommend the Steve Smith book (available in print or on his website) as a place to get started.
The best areas of Dr. Hayes' book are its treatement of sampling (better than John Proakis' book), z-transforms and DFT. I think the FFT treatment was okay and the filter design at the end was a little light, but that is okay since this is really intended for a first semester course. The main purpose of all the Schaum's books is to provide more worked out examples of tricky material and Hayes' book serves the purpose. One final thing, in the introduction, the author says to check out his website that has errata listed, but I typed the address in and got an "under construction" message.
