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 the Hamming window equation?

The following equation generates the coefficients of a Hamming window: w ( n ) = 0.54 − 0.46 cos ( 2 π n N ) , 0 ≤ n ≤ N .

What does hamming function do in Matlab?

hamming( Length ) returns a symmetric Hamming window object with length Length . Length must be a positive integer.

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.
