Abstract
An arrangement for suppressing amplitude variation in FM signals comprises a frequency divider which frequency divides an incoming FM signal to provide frequency divided signals having two discrete levels dependent upon the amplitude of the incoming FM signal in relation to a threshold value, and a frequency multiplier which combines the frequency divided signal to provide an output signal of substantially constant amplitude and having a frequency equal to that of the incoming signal.
