Abstract

PURPOSE:To increase the stability of circuit, by making the phase control circuit for electric signal constituted with a single phase circuit. CONSTITUTION:The phase of the input signal eH1 is delayed by thetaa and the signal eH1 becomes the signal eH2. The difference signal eH3 between eH1 and eH2 is obtained to the output of the transistor Q1 of differential pair to which signals eH1 and eH2 are input. The absolute value of eH3 is controlled with the differential amplifier of double balance type. The potential difference between the common base potential of transistors Q6, Q7 and that of transistors Q5, Q8 controls the relative absolute value of the signal eH3 according to the control voltage EC to obtain the vector addition output at the load resistor R3. Taking the signal eH1 as the APC output of color television, stable hue adjusting circuit is realized.
