Use this to reduce leakage of signals across frequency bands.

Properties

RectangularW[n] = 1.0.
TriangleW[n] = 1 - abs(2n/N - 1).
HammingW[n] = 0.54 - 0.46 * cos(2π * n/N).
HanningW[n] = 0.5 * (1.0 - cos(2π * n/N)).
BlackmanW[n] = 0.42 - 0.5 * cos(2π * n/N) + 0.08 * cos(4π * n/N).
BlackmanHarrisW[n] = 0.35875 - 0.48829 * cos(2π * n/N) + 0.14128 * cos(4π * n/N) - 0.01168 * cos(6π * n/N).
