It was one of the first big books out on DSP. It is a more mathematical book than many of the easy-to-read books that came along later (including one by O&S). It was complemented at the time by the more hardware/ implementation oriented book by Rabiner and Gold. Dirk Bell DSP Consultant

The kinds of things people do in military systems tends to be a lot different from most non-military work. I guess that in the 70s, 90% of all copies of O&S and Rabiner and Gold sold to people in military work, who had not studied anything about DSP at college - because very few colleges had begun DSP courses - and who needed to get a clue what they were doing. Its a while since I looked at either book, but I remember once reflecting on how the contents seemed to reflect that heritage. Steve

I would recomend them in this order: 1)Digital Signal Processing by Proakis and Manolakis (It is "easier" to follow the math than the O & S book) 2)Schaum's Outline of Digital Signal Processing by Hayes (DO ALL THE PROBLES WITH SOLUTIONS. This should then get you ready for the O & S Book) 3)Discrete Time Signal Processing by Oppenheim and Schafer and Buck (it one of the bibles in the field. There are some things here that are covereed like nowhere else).

I don't have Rabiner and Gold at hand right now, but IIRC it is biased towards the radar signal processing. When they give an example of a technique, they often mention some kind of military application. And yes, R&G used to be a handbook of people who actually worked on radars.
