I remember talking with the late Bob Pease about the state of the art in digital techniques for solving complex problems. He politely let me babble for a few minutes and then laughed, “Yep, I solved that same problem 10 years ago with two op-amps”. I wanted to crawl under something, but his office was completely full of every magazine he had ever received… but that’s another story. He was correct – sometimes a straight forward analog solution can not only be the most elegant, but also the most efficient. Sometimes you need the power of a DSP processor when systems are non-linear or the signal processing is not realizable in the analog domain. However sometimes simple analog circuitry can solve the problem. Don’t forget your roots. http://www.youtube.com/watch?v=Ww8_dqmr0bo
