scipy.signal.kaiserord¶
- scipy.signal.kaiserord(ripple, width)[source]¶
Design a Kaiser window to limit ripple and width of transition region.
Parameters: ripple : float
Positive number specifying maximum ripple in passband (dB) and minimum ripple in stopband.
width : float
Width of transition region (normalized so that 1 corresponds to pi radians / sample).
Returns: numtaps : int
The length of the kaiser window.
beta : float
The beta parameter for the kaiser window.

Notes
There are several ways to obtain the Kaiser window:
- signal.kaiser(numtaps, beta, sym=0)
- signal.get_window(beta, numtaps)
- signal.get_window(('kaiser', beta), numtaps)
The empirical equations discovered by Kaiser are used.
