Abstract: A color video signal recording system comprises a frequency modulator. A luminance signal is separated from an input color video signal. The amplitude of a color burst signal is intensified after it is separated from the input color video signal. The intensification is with respect to the amplitude of a carrier chrominance signal separated from the input color video signal. An automatic chroma control circuit receives the intensified color burst signal and the non-intensified carrier chrominance signal to effect level control. A specific level is not exceeded. A first frequency converter converts the frequency of the output signal of the automatic chroma control circuit. The converted signal is in a band which is lower than the band of said frequency-modulated luminance signal. The frequency-modulated luminance signal and the resulting output signal of said first frequency converter are mixed and multiplexed. A transducing head records the resulting mixed and multiplexed signal on a recording medium.

Abstract: An amplitude limiting circuit comprises a high-pass filter for passing the high frequency components of a frequency modulated video signal. The centerline of a signal portion has an amplitude width which is non-linear. A first amplitude limiter both limits and amplifies the output signal from the high-pass filter. A low-pass filter passes the low frequency component of the frequency modulated video signal. An adder adds the resulting output signals of the first amplitude limiter and the low-pass filter. A second amplitude limiter limits the resulting output of the adder.

Abstract: A color video signal recording system comprises a frequency modulator for frequency modulating a carrier with a luminance signal separated from an input color video signal. A frequency converter converts a carrier chrominance signal separated from the input color video signal. The separation provides a frequency band which is lower than the band of the frequency modulated luminance signal. Video heads successively record a mixed signal formed by mixing the frequency modulated luminance signal and the frequency converted carrier chrominance signal. Recording is made along a plurality of parallel tracks on a magnetic recording medium. The frequencies f1 and f2 are applied alternately to the frequency converter every time that the video heads scans the tracks. The frequencies f1 and f2 are selected at respective values which satisfy the equation f1 - f2 = (N/2)f.sub.H, where N is an odd integer, and f.sub.H is the horizontal scanning frequency.
