Understanding the FFT Algorithm | Pythonic PerambulationsThe Fast Fourier Transform (FFT) is one of the most important algorithms in signal processing and data analysis. I've used it for years, but having no formal computer science background, It occurred to me this week that I've never thought to ask how the FFT computes the discrete Fourier transform so quickly. I dusted off an old algorithms book and looked into it, and enjoyed reading about the dece
