value of Order and Fcutoff/Fs/2<br>
and what you are doing with hz (because iir does not call dbphi)<br>

Hello,<br>
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: <br>
hz = iir(Order,'lp','butt',Fcutoff/Fs/2,[0.1 0.1]);<br>
I get this error message:<br>
<br>
Singularité de la fonction log ou tan.<br>
at line 6 of function dbphi called by : <br>
[db_repf, phi_repf] = dbphi(repf);<br>
<br>
What did I miss ?<br>
No bugs have been reported for function dbphi, but three similar
bugs are listed for iir.<br>
Any suggestion welcome.<br>
