In a video reproducing apparatus having a head for reproducing a recorded frequency modulated signal and a frequency demodulator for demodulating the reproduced signal output from the head, a circuit interposed between the head and frequency demodulator comprises an adder having an input receiving the reproduced frequency modulated signal output from the head, a limiter connected between the output of the adder and the frequency demodulator for providing an amplitude limited output to the latter, and a feedback loop for also applying the amplitude limited output from the limiter to a second input of the adder so as to prevent occurrence of a reversing phenomenon and of an abnormal noise bar output, and thereby improve the reproduced picture quality.
