WebApr 25, 2013 · A 50 or 60 Hz notch filter is typically done as a twin-T filter. A passive twin-T has a poor Q-factor however, meaning that neighboring frequencies also will be attenuated, which can cause the ECG profile to be distorted. An active notch filter may look like this: Don't forget to recalculate the resistor values for 50 Hz; R1 will be 11.8 MΩ.
