20hz filter circuits

Can anyone point me to a passive differential notch filter circuit?
Everything I have found on the net is for a single ended circuit.
I want to filter the telephone ringer on a digital answering machine.

Thanks Guys.

Hi
You can design a differentiala notch filter use ANADIGM's FPAA ICs.
Very simple and free design software.
