In a video reproducing apparatus having a head (1A,1B) for reproducing a recorded frequency modulated signal and a frequency demodulator (8) for demodulating the reproduced signal output from the head (1A,1B), a circuit interposed between the head (1A,1B) and frequency demodulator (8) comprises an adder (12) having an input receiving the reproduced frequency modulated signal output from the head (1A,1B), a limiter (13) connected between the output of the adder (12) and the frequency demodulator (8) for providing an amplitude limited output to the latter, and a feedback loop (20,21) for also applying the amplitude limited output from the limiter (13) to a second input of the adder (12) so as to prevent occurrence of a reversing phenomenon and of an abnormal noise bar output, and thereby improve the reproduced picture quality. <IMAGE> |
