The text book by Alan Oppenheim is highly followed by many universities teaching DSP. Even though Qualcom is supplying the world, DSP based SOC's ,i see TI DSP chips are having a wide range of applications and also with better customer support.
Nice article. Having been around DSP for a while now, my view is that TI really made the Digital Signal Processor market happen, with their products and staying power. And what gave it a stamp as a market was Will Strauss started publishing market data (full disclosure, I know both Gene F. - a little - and Will S. - a lot :)
Thanks for the compliment. Dylan synopsized the DSP phenomenon well. And I agree that Frantz and Strauss did much to popularize the technology over the years, as a key developer and a reputable market follower, respectively.
