Abstract

PURPOSE:To enable to select the operation and inoperation of distortion detection loop, by providing the means disconnecting the distortion detection loop to enable to make inoperative the distortion detection loop taking into consideration of the characteristics of selectivity. CONSTITUTION:The selector switch 17 is placed between the output terminal of the modulation frequency oscillator 11 and the first input terminal of the local oscillator 4. On the other hand, the selector switch 18 operated in interlocking with the selector switch 17 is placed between the output terminal of the amplifier 16 and the second input terminal of the local oscillator 4. Further, the distortion detection loop is operated when the output of the oscillator 11 is fed to the first input terminal of the oscillator 4 and the output of the amplifier 16 is fed to the second input terminal of the oscillator 4 through the selection of the selector switches 17 and 18. Further, by interrupting the output of the oscillator 11 and the amplifier 16 to the input terminal of the oscillator 4, the distortion detection loop is made inoperative.
