Hey Fabs, I got problems with my filter design. I have a 13-order Butterworth low-pass with polynomials that are driving me nuts. Would you happen to have something up your sleeve for this? Oh, by the way, I hear that you now got stalkers on your tail. LOL! Even paradise has its black flies.

If it is a real circuit, then Spice, if it is just polynomials, then Mathcad. Or you could spend all your time writting something custom for this one problem using polynomial libraries. -- Jim Pennino

If you have a 13th order Butterworth there is no question you have
problems with your filter design.
