Filter, Notch

Filter, Notch

 

a type of rejection filter. A notch filter is a two-terminal network, usually a parallel resonant circuit, that is inserted into an electric circuit. The impedance of the network increases sharply in a certain relatively narrow frequency band. A notch filter attenuates alternating currents in the particular frequency band and transmits currents at frequencies outside the band.
