KaiserBetaWindowAtt Routine

Summary

Returns beta parameter for frequency analysis with the Kaiser window.

Declaration

Function KaiserBetaWindowAtt(Att: TSample): TSample;

Description

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);
