[Scilab-users] Newbie filter basics

[Michael Dunn]

Hi. Are there any resources or tutorials or references out there that would be helpful to  a newbie to SciLab filtering functions? I just want to filter some data – at this point, I don't even care what kind of filter – just want to learn how!

At first, I thought I'd try an IIR, but I couldn't figure out how to generate the coefficients.

//y = filter(num,den,x)


Then, I stumbled onto ffilt, which seems to generate FIR coefs, but where's the actual FIR filter function? Is it "convol"? I tried this:

plot(fft(convol(ffilt("hp",40,100),r)))

It does something, but I'm not sure what. Am I getting close?


Thanks,
