Abstract

Circuit for synchronization of the reference carrier frequency oscillator 3 in a PAL colour television receiver, where the oscillator 3 is further synchronized by the colour carrying frequency signals FU at the output of the PAL matrix. In accordance with the invention the sign in question for these signals is determined by evaluating the amplitude and polarity if the colour signals obtained by the demodulation and either the signal FU or the inverted signal FU-bar is taken to the phase comparison stage 7 in the PLL circuit 3, 7, 8. <IMAGE>
