I included it last time, but here is txt-file.
% The following 3 lines produce filter coefficients shown in Table 6.1.
wp = [0.35,0.65]; ws = [0.25,0.75]; Rp = 1; As = 50;
[N, wn] = ellipord(wp, ws, Rp, As);
[b,a] = ellip(N,Rp,As,wn);
w = [0:500]*pi/500; H = freqz(b,a,w); magH = abs(H);
magHdb = 20*log10(magH);
This code works OK for me!I get the results shown in the attached file

Hi
I have problem to use Octave 4.0.0 version's function ellipord.m (signal
package version 1.4.0?). File included. I get error
"validate_filter_bands". My operation system is Linux Xubuntu 16.04.
What is my fault?
Tarmo
Thank you for starting a new thread.Octave 4.0.0 is very old, and lots of thing have been fixed since then.I think you should upgrade to the newest octvae.
