These filters reject/attenuate signals in a specific frequency band called the stop band frequency range and pass the signals above and below this band. For example, if a Notch Filter has a stop band frequency from 1500 MHz to 1550 MHz, it will pass all ...
WebTwin-T notch filter. Figure 55 shows a passive notch filter, the twin-T filter, which has already been seen as part of the circuit of Figure 46. The center frequency of this circuit is f0 = 1/ pi RC. This is the frequency at which the signals passing along the two networks become 180° out of phase with each other and therefore cancel out.
