Abstract :
Four topologies for the realization of tracking notch filters for FM interference suppression are analyzed. Currently disclosed interference suppressors which utilize only an estimate of the instantaneous frequency of the interfering signal fall into one of these topologies. All topologies perform equally well when ideal components are used, but some have advantages when limitations of the analog components are considered
