Hello, I'm developing an FFT algorithm for impedance calculations. I searched the net and found very long and sophisticated codes and libraries for that like https://www.fftw.org I don't want to use pre-written libraries. I just want to know the very basic idea so I can find out what differences with DFT it has so hopefully I can write an algorithm in C with a few dozen lines.
Can someone give me a hint what keyword or what site I should look for the core idea of FFT?
thanks alot.
