455 kHz ceramic discriminator is a component commonly used in radio receivers, particularly in AM (amplitude modulation) radios.
The use of a ceramic material in the discriminator helps to provide stability and accuracy in the demodulation process,
as ceramic materials can have well-defined resonant properties at specific frequencies.

Item Requirements
Distortion (at 455 KHz) 2.0% max
Recovered Audio 3dB Bandwidth (from 450KHz) �±4.0 KHz min.
Recovered Audio Output Voltage (at 455KHz) 100 �± 40 mV
Test Method
Input signal Condition
Input level : 80dB
Frequency Deviation : �±4.0KHz
Modulation Frequency : 1 KHz
Recovered Audio
Input the above signal and sweep the carrier frequency
3dB Bandwidth around 455 KHz and find out the maximum audio output frequency.
Then sweep the carrier frequency again and find two frequencies which are observed -3dB attenuation points from the maximum point .
Higher frequency point is called (f1) and lower called (f2), (f1-455KHz)is defined as upper 3dB bandwidth and (455Khz-f2)
Recovered Audio Recovered audio
output voltage shall be measured Output Voltage when the carrier frequency is adjusted to 455KHz.
The Distortion Carrier frequency is adjusted to 455Khz. And then , distortion shall be measured with 1 kHz modulation frequency
