Oh, but I'm not looking into hardware. I'm a software only kinda guy :)

Dammit! Lol!
I think I didn't really pose my question the right way :))
What **are** these schematics?? Am I so wrong in thinking that they only
model filters? Everyone starts talking about nonlinearities, and here I
was thinking these were filters :)


cheers,
