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.

WebThere is no constraint on window type, only that the window overlap-adds to a constant for the hop size used. In particular, always yields a constant overlap-add for any window function. We will learn later (§8.3.1) that there is also a simple frequency-domain test on the window transform for the constant overlap-add property. Web10 apr. 2024 · end.
