Abstract

PURPOSE:To improve the characteristic for noise and make it possible to resolve transversal noise generated for receiving of a weak electric field conventionally, by controlling the inversion phase of the FF by a DC voltage in the color signal circuit of the color TV receiver. CONSTITUTION:The output of substractor 5 separated from B-Y signal components is not only given to R-Y demodulator 9 but also applied to the second burst gate circuit 21. and only the burst signal is extracted there. The burst signal extracted by gate circuit 21 is inverted for every line by phase inverting means 22. This inversion operation is performed by the output of FF19. Meanwhile, the subcarrier wave generated by subcarrier wave oscillator 13 has the phase shifted by +90 deg. phase shifter 35 and is applied to phase detector 23. Therefore, when the burst signal is given, the output of phase detector 23 is generated as a -pulse. Consequently, this pulse is integrated in 24 and becomes a -DC voltage, and FF19 is controlled by this DC voltage.
