Two software packages are giving me different values of poles and zeros for the same elliptic filter. One of these programs seems to be behaving very weirdly. Will someone with a filter design program try this and send me the poles and zeros for comparison: Order of filter: 5 Passband cutoff: 10 kHz Passband Ripple: 1 dB Minimum attenuation in stopband: 40 dB Thank you.
