Description

Spectrum analysis windowing types.

Use this to reduce leakage of signals across frequency bands.
Variables
Rectangular W[n] = 1.0.
Triangle W[n] = TRI(2n/N).
Hamming W[n] = 0.54 - (0.46 * COS(n/N) ).
Hanning W[n] = 0.5 * (1.0 - COS(n/N) ).
Blackman W[n] = 0.42 - (0.5 * COS(n/N) ) + (0.08 * COS(2.0 * n/N) ).
BlackmanHarris W[n] = 0.35875 - (0.48829 * COS(1.0 * n/N)) + (0.14128 * COS(2.0 * n/N)) - (0.01168 * COS(3.0 * n/N)).
