Abstract: 1,183,505. Colour television; transistor gating circuits. R.C.A. CORPORATION. 8 Aug., 1967 [21 Sept., 1966], No. 36473/67. Headings H4F and H3T... Opposite polarity video signals are applied from a phase splitter stage 52, 53 through driver stages 54, 55 to gate stages 56, 57 which are rendered conducting alternately by pulses 36, 37 from a generator 38, whereby there is obtained at an output 21 a video signal which alternates in polarity. In the particular arrangement described, generator 38 operates at line rate and the video signal comprises the red colour difference signal intended for application to a subcarrier modulator in a PAL colour television system. The black levels of the signals from gates 56, 57 are determined by the potentials at which diodes 63, 59 limit the positive excursions of pulses 36, 37. In accordance with the invention, the black level of one polarity of output signal (that from gate 56) is controlled automatically to equal the black level of the other by adjusting the limit potential for diode 63. Normally conducting transistors 78, 72 are rendered non-conducting during line blanking intervals (when the video signal is at black) by pulses from generator 45 and allow potentials proportional to the gate output signals to be applied via transistors 81 and 76 (alternately as the two gates conduct) to charge capacitors 82 and 77. `The potentials on the capacitors are compared in differential circuit 83, 84 and any difference operates via amplifier 67 to modify the potential applied to the anode of diode 63.
