Abstract
A color subcarrier generator used with a system for converting data representing color displays into a composite color video signal suitable for display by a visual display apparatus comprises an oscillator which generates a system clock signal with a predetermined frequency, a frequency divider responsive to the system clock signal from the oscillator which generates horizontal and vertical sync signals for the visual display apparatus and a dot clock signal for timing sequential dots of the horizontal lines of the composite color video signal into which the data is converted and a subcarrier generating circuit which generates a color subcarrier signal to be included in the composite color video signal and which is synchronized in phase with the horizontal sync signal.
