Hi. I have some problems
using scilab signal processing and I hope you cand help me. I have read
your book and i still haven't found the answer.
Here it's my problem.
I have a couple of informations about 3 filters. I don't know how to
implement
the residue and pole imaginary
part in an transfer
function and the plot
the filtred signal, it simply doesn't work.
Pls give me an
example if you may, so i have something to start with.
Thank you
a lot.
