Web12 nov. 2013 · The window function reduces the signal to zero at the end points of the data record. This reduces the discontinuities that cause spectral leakage. Different window functions are available... WebWindowing is used because the DFT calculations operate on the infinite periodic extension of the input signal. Since many actual signals are either not periodic at all, or are sampled over an interval different from their actual period, this can produce false frequency components at the artificial 'edge' between repeated intervals, called leakage.

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. pinprick rash on lower legs
