scipy.signal.kaiserord

scipy.signal.kaiserord(ripple, width)

Design a Kaiser window to limit ripple and width of transition region.

Parameters :

ripple – positive number specifying maximum ripple in passband (dB) :

and minimum ripple in stopband

width – width of transition region (normalized so that 1 corresponds :

to pi radians / sample)

Returns :

N, beta – the order and beta parameter for the kaiser window. :

signal.kaiser(N,beta,sym=0) returns the window as does signal.get_window(beta,N) signal.get_window((‘kaiser’,beta),N)

Uses the empirical equations discovered by Kaiser. :
