Ceramic Discriminators Application Notes
Application Notes of
Ceramic Discriminator
What is Discriminator
The discriminator functions to convert the change of the frequency into audio frequency, an unique
system of detection only used for FM broadcasting. The detection of FM wave is made through the
circuit in which the relation between the frequency and the output voltage is linear. FM wave
detection methods as known as ratio detection, Foster-Seeley detection, quadrature detection,
differential peak detection, etc.
FM Wave Detection Methods
 Ratio Detection
Ratio detection is the most popular method in use at present. The impedance characteristic of a
ceramic resonator is designed into the circuit, then a coil as a detector is unnecessary. The fact is
that adjustment is eliminated.
 Quadrature Detection
This detection method was originally developed as a sound detector for TV sets, but recently it
has become popular in the consumer market (FM tuners, car radios, etc.). The Quadrature
Detection Method utilizes the phase characteristic.
An FM signal is supplied directly to one side of the multiplier’s input with an IC to the other side
of the multiplier’s input an FM-IF signal, which is passed through the phase shifting circuit
mainly composed of a tank circuit tuned to FM-IF, is applied. By taking advantage of the phase
characteristic of the ceramic resonator as a ceramic discriminator, we can eliminate adjustment
of the FM-IF circuit.
 Differential Peak Detection
This detection method was developed by RCA as a sound detector for TV sets. The method has
follow ing features.
1. Can output large level.
2. Can function with only 1 synchronous coil.
Non-linearities of synchronous characteristics are compensated each other by applying rectified
intermediate frequency voltage. Thus, linearity can be obtained.
