Abstract

PURPOSE: To obtain the good reproduction signal even to the SECAM signal and CCIR black-and-white television signal with the color killer circuit and gate circuit with a simple constitution, without guard band between the recording tracks.
CONSTITUTION: After the chrominance signal (frequency fc) being the output of the band filter 3 passes through the inverse bell filter 19 to obtain flat amplitude characteristics, it is shaped at the limiter 20 and the carrier frequency is divided into fs(=fc/4) with the frequency divider 17. Further, the higher harmonics are eliminated at the low pass filter 21 and it passes through the recording equalizer 21 to obtain the same amplitude characteristics as the output of the band pass filter 3. Furhter, to reject the noise in the signal, the envelope of the chrominance signal being the output of the filter 19 is detected at the envelope detector 29, the gate signal is formed with the gate signal forming circuit 30, and after noise is removed by gating the blanking of the output signal of the circuit 21 with the gate circuit 31, it is superimposed on the luminance signal in frequency modulation fed via the high pass filter 5 and recorded.
