SignalUtils.KaiserBetaWindowAtt Method

function KaiserBetaWindowAtt(Att: Double): Double;

Returns beta parameter for frequency analysis with the Kaiser window.

#NameTypeDescription
1AttDoublescalar

Returns: Double

Remarks:

Compute Beta parameter for the Kaiser window applied to the signal, where spectral leakage is attenuated at least Att decibels. Attenuation is estimated from ripple as:

Att[dB] = -20*Log10(Ripple);

Ripple = Exp10(Att/-20);
