SignalUtils.CosineTappered Method

Cosine tappered window.

Syntax
C#
Visual Basic
public static TVec CosineTappered([In] TVec Src, double Percent, int Index, int Len);

Applies Cosine tappered 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. When percent parameter is 100, the CosineTappered window becomes equal to the hanning window. When the Percent parameter is 0, then the window remains rectangular (box car).
