I've got a FIR filter, which I developed in IC. Now, when I got my results, I ended up with two signals:
- Theoretical signal calculated through MATLAB as a response to my input.
- Real response given by the hardware.
What is the best method of calculating the error of the real response with respect to the theroetical one?
I could go
delta = abs(Y) - abs(Yreal); max_err = max(delta);
but I don't know what to do with the maximum error? Any suggestions?
