WebFFTW is a class for computing the complex N-Dimensional DFT or inverse DFT of an array using the FFTW library. The interface is designed to be somewhat pythonic, with the correct transform being inferred from the dtypes of the passed arrays. WebJun 24, 2012 · 11. To convolve 2 signals via FFT you generally need to do this: Add as many zeroes to every signal as necessary so its length becomes the cumulative length of the original signals - 1 (that's the length of the result of the convolution). If your FFT library requires input lengths to be powers of 2, add to every signal as many zeroes as ...
