scipy.signal.kaiser_beta¶

scipy.signal.kaiser_beta(a)[source]¶

Compute the Kaiser parameter beta, given the attenuation a.

Parameters :

Parameters :	a : float The desired attenuation in the stopband and maximum ripple in the passband, in dB. This should be a positive number.
Returns :	beta : float The beta parameter to be used in the formula for a Kaiser window.

a : float

The desired attenuation in the stopband and maximum ripple in the passband, in dB. This should be a positive number.

Returns :

beta : float
