What does a Hamming window do?
The Hamming window is a taper formed by using a raised cosine with non-zero endpoints, optimized to minimize the nearest side lobe. Number of points in the output window. If zero or less, an empty array is returned. When True (default), generates a symmetric window, for use in filter design.
What is Hamming and Hanning window?
The Hamming window is an extension of the Hann window in the sense that it is a raised cosine window of the form. (A3.10) with a corresponding spectrum of the form. (A3.11) The parameter a permits the optimization of the destructive sidelobe cancellation mentioned in the description of the Hann window.
