摘要： A PLL video detector comprises a phase detector circuit receiving a video intermediate frequency signal and an oscillation output of a VCO for phase-detecting the same. The phase of the oscillation output of the VCO is controlled by a signal obtained by smoothing a detection output of the phase detector circuit by a low-pass filter. In addition, a trap circuit having a center frequency of f.sub.H is provided between the phase detector circuit and the VCO, so that an unecessary component having a frequency of f.sub.H is removed from an output signal of the low-pass filter. Consequently, the VCO stably oscillates, so that occurrence of a buzz sound in a sound output and degradation of the picture quality can be prevented.

摘要： A PLL frquency synthesizer system television signal receiving apparatus includes a tuner, a control circuit for controlling a channel selecting operation by the tuner, and an intermediate frequency processing circuit for subjecting the IF signal outputted from the tuner to an intermediate frequency processing. The control circuit controls oscillating frequency of a local oscillating circuit in the tuner based on the PLL frequency synthesizer system. The intermediate frequency processing circuit includes an AFT signal detecting circuit for detecting a deviation of the IF signal frequency from the standard carrier frequency and feeding back the same to the control circuit. The AFT signal detecting circuit has an AFT coil which radiates higher harmonics. After a channel selection by the control circuit is completed, the AFT signal detecting circuit is rendered non-operative, so that beat interference appearing on a reproduced picture caused by the higher harmonics from the AFT coil are prevented.
