ABSTRACT:
An apparatus for detecting and compensating for the drop-out in a video tape recorder in which an FM audio signal is recorded on a magnetic tape and is reproduced therefrom utilizing a rotary magnetic head. In a playback mode, a frequency demodulator demodulates the reproduced FM audio signal. The reproduced FM audio signal is supplied to a synchronous detector and synchronously detected with an output signal of the frequency demodulator. An output signal of the synchronous detector is supplied through an integrator to a drop-out discriminator which detects a drop-out generating period and provides an output indicative thereof.
