FFT Review

January 20, 2010

I haven’t done signal processing of any sort for a while now (that’s not to say I ever did very much of it) – but I occasionally find myself needing to do some filtering or frequency spectrum analysis. And as usual, I always need to look up how I did it before. I should really write myself a little cheat sheet. But since I don’t have time for that now, here’s a quick link: FFT Tutorial. It’s from someone in the EE department at the University of Rhode Island. I had a quick look and I like it because it provides some theory, and also a Matlab example (and it’s pretty clearly written using LaTeX – yeah!). And while I’m on the topic of signal processing, here’s a link to a tutorial by Richard Lyons: “Quadrature Signals, Complex but not Complicated“. I like this one because it has a movie trivia question on page 3. And I totally knew the answer without looking.
