Abstract
A video signal processing circuit for reproducing an FM video signal. A video reproduction signal output from a magnetic head is supplied to a low-pass filter, which extracts a chroma signal. The video reproduction signal is also supplied to a chroma signal removing circuit through a high-pass filter of low degree and sharpness. The chroma signal removing circuit removes the chroma signal component. The output of the chroma signal removing circuit is amplitude-limited to a predetermined degree by a limiter, and then supplied to a demodulator which extracts a luminance signal.
