Abstract

PURPOSE: To facilitate the discrimination as to whether a synchronous oscillator operates normally or not by making a video amplifier have a narrow-band characteristic.
CONSTITUTION: With the frequency characteristic of the video amplifier 10 being made to be of narrow band, the component of beat which is generated when the synchronous oscillation is not normal is removed. In the case when the synchronous oscillator 3 does not make synchronous oscillation normally, the component of beat of a detecting output is removed, the waveform of the input to a sample hold circuit 11 turns to be averaged waveform, and an amplitude is made to be fixed even when the amount of phase shift of a variable phaser 5 is changed. Meanwhile, in the case when the synchronous oscillator 3 makes synchronous oscillation normally, the component of beat is not produced. Therefore, the oscillator is not influenced by the narrow-band characteristic of the video amplifier 10, and when the amount of phase shift of the variable phaser 5 is changed, the amplitude of the output of the video amplifier 10 is changed from zero to a certain value.
