60hz notch filter circuit. The 60 Hz notch filter is designed using several op amp. Some of them are to realise the Low pass filter, some of them to realise the high pass filter. The IC UAF42 is used to get rid of such complicated circuit. The value of registers and capacitors are given within the circuit diagram.
Variable Notch Filter Circuit - Making Easy Circuits

This variable notch filter circuit for enabling an adjustable audio frequency cancellation as desired by a specific application. A Notch Filter can also be named as Band Stop filter or Band Reject Filter. Most of these filters cancel/attenuate signals in a particular frequency band referred to as stop band frequency range and allow the signals over and below this band.

A Notch filter is nothing but a narrow band-stop filter. If the stopband of band-stop filter is very narrow and highly attenuated over a few hertz, then that special type of band-stop filter is known as Notch filter. Since the stopband of Notch filter is narrow up to a few Hz so the Notch filter is also known as Narrow band stop filter in some cases.
