Detectors 103
Detectors 103 : Particle Detectors: (4.6) Detector (Radio): (2) Frequency and Phase Modulation Detectors: (2. 1) Phase Detector: A phase detector is a nonlinear device whose output represents the phase difference between the two oscillating input signals. It has two inputs and one output: a reference signal is applied to one input and the phase or frequency modulated signal is applied to the other. The output is a signal that is proportional to the phase difference between the two inputs. In phase demodulation the information is contained in the amount and rate of phase shift in the carrier wave
