Abstract

PURPOSE:To obtain the high-S/N reproduced signal with reduced crosstalk and no inverse phenomenon, by applying the low-band carrier chrominance signal to the limiter to have the amplitude limitation and then piling the chrominance signal onto the FM luminance signal for recording. CONSTITUTION:In case the crosstalk is eliminated for the chroma signal which is converted into the low frequency of the SECAM-system colot TV and separated through BPF2, the chroma signal is made to pass through reverse bell filter 12 to secure the flat amplitude characteristics and then receives the shaping through limiter 13. After this, carrier frequency is divided into 1/4 via 4-divider 14. Then the division output is applied to record equalizer 16 and then led to limiter 21 to give limitation to the amplitude of the upper and lower parts, and the output is piled onto the FM luminance signal for recording. In such way, the high-S/N reproduced signal can be obtained with the reduced crosstalk and no inverse phenomenon.
