cupynumeric.blackman#

cupynumeric.blackman(M: int) → ndarray#

Return the Blackman window.

The Blackman window is a taper formed by using the first three terms of a summation of cosines. It was designed to have close to the minimal leakage possible. It is close to optimal, only slightly worse than a Kaiser window.

Parameters:: M (int) – Number of points in the output window. If zero or less, an empty array is returned.
Returns:: out – The window, with the maximum value normalized to one (the value one appears only if the number of samples is odd).
Return type:: ndarray
