Blackman-Harris window.

Pascal
function BlackmanHarris(const Src: TVec; WindowMode: TSignalWindowMode): TVec; overload;
File
Description

Applies BlackmanHarris window to Src. Window functions are applied to the signal prior to conversion to frequency domain with the FFT algorithm, to reduce the spectral leakage. Their side-effect is a lower frequency resolution. 

w[n] := 0.42323 - 0.49755*cos(2*Pi*n/(n-1)) + 0.07922*cos(4*Pi*n/(n-1)) 

0 <= n <= M - 1
