Hi,

I have a signal to process with a band-pass butterworth filter. I know how to do it on Matlab ( [b,a] = butter(n,Wn,ftype) )but not in Scilab...

Can someone give me some way to do it, or some doc but first explain me how it works ?

My signal is a 7min duration EMG at 500Hz with regular peak (Dynamic EMG)

Thanks !
