Abstract :
The behaviour of a quadrature oscillator when subjected to a synchronizing signal has been analysed and experimentally studied in depth. It has led to the development of a single shot tracking FM discriminator with excellent interference rejection capability. It can also be used as a phase locked demodulator exploiting tracking capability.
