A band reject or band stop filter is one which does not allow a specific band of frequencies to pass through it. It is also known as Notch filter, owing to the shape of its frequency response curve. This filter thus reject a narrow frequency range and allows all other frequencies. The name twin T is due to the twin T RC filters attached to each other via Ground.
In this tutorial, we will build a band reject filter for rejecting 50-60 Hz AC supply hum. We will see the circuit, do a simulation and finally make the circuit practically and will finally compare the simulated and practical results.
