function KaiserBetaWindowAtt(Att: Double): Double;
Returns beta parameter for frequency analysis with the Kaiser window.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Att | Double | scalar |
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);
