WitrynaOptimize FFT with Padding. Use the nextpow2 function to increase the performance of fft when the length of a signal is not a power of 2. Create a 1-D vector containing 8191 sample values. rng default ; x = rand ( [1,8191]); Calculate the next power of 2 higher than 8191. p = nextpow2 (8191); n = 2^p. n = 8192. Pass the signal and the next …Witryna12 paź 2024 · 1 Answer Sorted by: 1 As written in Matlab pwelch document, by using an integer for window, a Hamming window of length window (integer) will be used. Also the nfft in python should set to the next power of two greater than length of window.
