SYNC SIGNAL GENERATING SYSTEM FOR LINE-SWEEP TELEVISION RECEIVERS; SYSTEM FOR GENERATING CLOCK-PULSE SIGNAL IN LINE-SWEEP TELEVISION RECEIVER; SYSTEM FOR GENERATING CLOCK SIGNAL SYNCHRONIZED WITH DISPLAY UNIT IN TELEVISION EQUIPMENT Russian patent published in 1999 - IPC

FIELD: television receiver synchronizing devices. SUBSTANCE: sync signal generating system has line synchronization signal generating unit and video signal source, horizontal-deflection unit, single and double clock frequency converter. In system, line- sweep signal is not always synchronized with line synchronization component of input video signal; oscillating unit generates signals at frequency which is a multiple of line synchronization component of input video signal. EFFECT: improved design. 14 cl, 11 dwg
