Abstract
PURPOSE: To change phase of the burst signal and to make shifting to IC simple, by changing relatively the bias of one and the other transistors which form the differential amplifiers in the color television camera.
CONSTITUTION: To the constant-current source 11 of the differential amplifiers 21, 31 is supplied the burst flag pulse which turns ON the foregoing during the burst period, in the input terminals of the differential amplifiers 22, 23 and 32, 33 are supplied the color subcarrier signals which are different in phase, respectively, and the burst signal is taken out after outputs of the differential amplifiers 24, 25 and 34, 35 are compounded. And the bias of one and the other transistors which form the differential amplifiers 21, 31 is changed relatively, and the phase of the burst signal is changed.
