Hi, thanks for the solution, maybe i'll try with a different transformer to shift the cutoff.

Blame it on my bad English... In fact it's partially true: to test a FIR the easiest solution (that i know) is to send a square-ware as input and observe the output.... but if the signal is deformed (at the limit it's looking like an integration), measures are difficult.
