scipy.signal.kaiser_atten¶
- scipy.signal.kaiser_atten(numtaps, width)[source]¶
Compute the attenuation of a Kaiser FIR filter.
Given the number of taps N and the transition width width, compute the attenuation a in dB, given by Kaiser’s formula:
a = 2.285 * (N - 1) * pi * width + 7.95Parameters: numtaps : int
The number of taps in the FIR filter.
width : float
The desired width of the transition region between passband and stopband (or, in general, at any discontinuity) for the filter.
Returns: a : float
The attenuation of the ripple, in dB.
