WebBlackman, flat top, Hamming, Hann, and rectangular windows are all special cases of the generalized cosine window . These windows are combinations of sinusoidal sequences with frequencies that are multiples of 2π/ (N – 1), where N is the window length. One special case is the Blackman window: WebMay 25, 2012 · Here the flat-top is about as bad as it gets (unless you are really trying to be bad), and so most of the named window functions do better. Arguing for Hann versus Hamming versus Bartlett versus whatever is trickier, the bottom line is they are all better than the Flat Top. Other places to read:
