ABSTRACT:
There is disclosed a noise eliminating device for an angle-modulated wave, in which a carrier amplitude fluctuation of an angle-modulated input wave is detected in a frequency difference detector to obtain a frequency variation signal corresponding to a frequency variation arising at an amplitude limiter from the carrier amplitude fluctuation. Noise caused by the amplitude fluctuation is eliminated from the angle-modulated input wave by subtracting the frequency variation signal from an output signal of the amplitude limiter after or before the frequency difference detector.
