Abstract
PURPOSE:To perform reception in minimum distortion to input FM signal at all times, by providing the variable voltage setter in which the oscillation frequency of the local oscillator can be changed with superimposing on the output voltage of the distortion detection loop. CONSTITUTION:The variable voltage setter 17 is connected between the output terminal of the amplifier 16 and the second input terminal of the local oscillator 4, the set voltage of the variable voltage setter 17 is superimposed on the output voltage of the amplifier 16, and it is fed to the second input terminal of the local oscillator 4. By setting the output voltage of the variable voltage setter 17, the distortion in the means modulating the intermediate frequency signal is cancelled to enable to adjust the frequency of the local oscillator 4 having minimum distortion to the input FM signal at all times.
