What is FM Ratio Detector Overview and Analysis about?
The ratio detector was commonly used as an FM demodulator in radio receivers using discrete components. It provided good performance with few components compared to other detectors like the Foster-Seeley detector. The ratio detector offered better rejection of amplitude modulation and noise immunity. Its operation centered around a frequency sensitive phase shift network with diodes and a transformer. It detected changes in signal frequency by exploiting the phase difference between transformer windings. Wh
