RE: Spectrum analysis (Fourier)
You're looking for the FFT (Fast Fourier Transform) algorithm. I'd give you more info, but I've loaned out the book I had for it. Google FFT, and you should be able to find what you're looking for.
There are some constraints, such as needing 2^n digitized samples and a couple other things, but it's definitely doable. |
