Detectors 107
Detectors 107 : Particle Detectors: (4.6) Detector (Radio): (2) Frequency and Phase Modulation Detectors: (2. 5) Other FM Detectors: Less common, specialized, or obsolescent types of detectors include: (a) Travis or double tuned circuit discriminator using two non-interacting tuned circuits above and below the nominal center frequency; (b) Weiss discriminator which uses a single LC tuned circuit or crystal; (c) Pulse count discriminator which converts the frequency to a train of constant amplitude pulses, producing a voltage directly proportional to the frequency
