The figure shows the 60Hz notch filter consist of INA110 and double-T network. The 2kΩ potentiometer can adjust Q in this circuit. When the frequency of the city electricity is 50Hz, the resistance of this filter need to be changed, 5.34MΩ into 6.37MΩ and2.67MΩ into 3.16MΩ.This circuit can filter out the AC noise from the circuit.
