Detectors 105
Detectors 105 : Particle Detectors: (4.6) Detector (Radio): (2) Frequency and Phase Modulation Detectors: (2. 3) Ratio Detector: The ratio detector is a variant of the Foster-Seeley discriminator, but one diode conducts in an opposite direction. The output in this case is taken between the sum of the diode voltages and the center tap. The output across the diodes is connected to a large value capacitor, which eliminates AM noise in the ratio detector output. While distinct from the Foster-Seeley discriminator, the ratio detector will similarly not respond to AM signals, however the output is only 50% of the output of a discriminator for the same input signal
