вот для других есть
например для Баттерворта - это
BUTTORD Butterworth filter order selection.
[N, Wn] = BUTTORD(Wp, Ws, Rp, Rs) returns the order N of the lowest order digital Butterworth filter
.
для Бесселя есть же только:
BESSELF Bessel analog filter design.
[B,A] = BESSELF(N,Wo) designs an N'th order lowpass analog Bessel
filter and returns the filter coefficients in length N+1 vectors B and A. The frequency Wo is the frequency up to which the group delay is approximately constant.
и
BESSELAP Bessel analog lowpass filter prototype.
[Z,P,K] = BESSELAP(N) returns the zeros, poles, and gain
for an N-th order normalized prototype Bessel analog
lowpass filter.
.
а какое N им подсовывать - непонятно :(
