This filter allows you to remove frequency band from a signal. In the example below, we’ll design a 50Hz notch filter. This allows us to remove the 50Hz hum picked up by, say, a microphone cord. Of course, it can be easily designed for 60Hz as well.

The following circuit is designed for filtering 15 volt supplies like those typically found in instrumentation. The shunt will greatly reduce white noise, spurious signals, and line-related signals on the power supply; the attenuation can exceed 40 dB with careful construction. The values are not critical except that the gain of the amplifier should be [...]
