-
syntfil[Cauer_asnew] - compute the new value of the stopband attenuation
Calling sequence:
Cauer_asnew(order, Os, ap)
Parameters:
order - order of the Cauer approximation [-]
Os - stopband frequency of normalized lowpass (NLP) [1/s]
ap - passband ripple [dB]
Parameter order must be positive integer. Parameters Os a ap must be positive number, where Os > 1 .
