> I would venture most of us haven't thought of it since college Not sure what kind of engineering work you are doing, but I can vouch that your assessment is incorrect in general for any kind of engineering work, be it CS related or not. I've (n=1) had to think about the FT a very large number of times in my engineering career, be it for image processing, computer graphics, or any time there is some sort of time-based signal to deal with and understand. A bunch of colleagues working on radar tech, FT and related concepts are their daily bread. Anyone doing actual EE - same thing, it's always there lurking in the background Now sure, if what you do all day is react-type stuff, then yeah, maybe. Physicists - same thing, how can you possibly look at any kind of physical process and not at the very least think how the thing looks like in the frequency domain?
