Abstract

PURPOSE: To prevent the generation of a lateral-line noise by a noise, by driving FF, which provides inversion control of a PAL switch, by horizontal pulses.
CONSTITUTION: A chrominance signal and burst signal are inputted to input terminal 1 and this burst signal is separated into two kind of burst signals by separating method 23 driven by output pulse P2 of FF 22 inverted, line by line, by horizontal pulse P1, and then supplied to 1st and 2nd subcarrier oscillators 29 and 30. The outputs of oscillators 29 and 30 are supplied to adder 31 and subtracter 32 and the output of adder 31 is also supplied as a B-Y demodulation subcarrier to B-Y demodulator 8 through 180°-phase shifter 33. For the use as a R-Y demodulation subcarrier, on the other hand, the output of subtracter 32 is branched to line 35 equipped with 180°-phase shifter 36 and direct line 34, which are connected to contacts (a) and (b) of switch method 37 inverted, line by line, by pulse P2, and from those points, signals are supplied to R-Y demodulator 9 with the phase position alternated, line by line, between R-Y and -(R-Y).
