Hello,
I am beginning to use digital filters to treat some data. As my first
step, I try to run the examples in the help,how to design an elliptic
filter (using Scilab 5.5.1, Win7-64). This works . However, when I
select a Butterworth filter:
hz = iir(Order,'lp','butt',Fcutoff/Fs/2,[0.1 0.1]);
I get this error message:
Singularité de la fonction log ou tan.
at line 6 of function dbphi called by :
[db_repf, phi_repf] = dbphi(repf);
What did I miss ?
No bugs have been reported for function dbphi, but three similar bugs
are listed for iir.
Any suggestion welcome.
