Abstract
PURPOSE: To control the hue easily, by using the variable resistor to the hue control circuit in the color receiver, through continuous phase shift for the subcarrier signal according to the DC voltage obtained at the rotor of the variable resistor and the signal delayed in phase by 90° from the subcarrier signal.
CONSTITUTION: The subcarrier oscillator 1 oscillates the subcarrier signal S0, the phase detector 2 controls the oscillator 1 with the phase difference between the burst signal of the video signal fed to the input terminal 2a and the output signal S0 of the oscillator 1, the signal S0 is fed to the 90° phase shift circuit 3 and the subcarrier signal S1 delayed in phase by 90° can be obtained. Further, at the junction point a of each collector of transistors Tr 7a, 24b, and at the junction point b of each collector of Tr 7b, 23b, the signal in phase shift for the signals S0 and S1 according to the DC voltage obtained at the rotor 11a of the variable resistor 11 is obtained. Thus, in the hue control circuit of a color TV receiver, the hue can easily be controlled by using the variable resistor.
