WebThe fast Fourier transform (FFT) is a computationally efficient method of generating a Fourier transform. The main advantage of an FFT is speed, which it gets by decreasing the number of calculations needed to … WebOct 3, 2013 · 1 Answer. Your fft command is wrong. The second argument is the FFT length, not the window. Y = fft (X,n) returns the n-point DFT. fft (X) is equivalent to fft (X, n) where n is the size of X in the first nonsingleton dimension. If the length of X is less than n, X is padded with trailing zeros to length n. If the length of X is greater than n ... WebDec 31, 2013 · Choosing the right overlap for a window function. On Wikipedia there is quite a list of window functions. However, when you are doing a lot of STFTs, you often have to have some overlap to get better results.
