Drivate of noisy signal

Started by raffaelemalutta February 7, 2002
Hallo evedybody.

I'm working with Simulink (discrete time) and I've to derivate a
noisy signal.

What is the best way to do this?

Anyone could suggest me a proper choise for cefficients of a
derivative filter?
(for example: [z(n) + 3z(n-1) -3z(n-2) -z(n-3)]/(6*h)) Thanks a lot
Bye
