发明名称 DEVICE FOR AUTOMATIC COMPENSATION OF PARASITIC COMPONENTS IN VIDEO SIGNAL OF BROADCASTING TV SYSTEM
摘要 FIELD: TV equipment. SUBSTANCE: generators of line and frame compensation signals are designed using identical circuits and are equipped with introduced saw-tooth signal generator, which input receives frame (line) synchronization signal, differential adder, and three inverting repeating circuits, first of which is connected to functional input of signal compensation unit, while input of second of which is connected to integration unit. In addition device has second differential adder, and two T-shaped resistor circuits, which symmetrical arms contain pairs of temperature-sensitive indirect heating resistors. Output tap elements of both T-shaped circuits are connected to final accumulation circuit, which output simultaneously serves as output of unit for generation of frame (line) compensation signal. EFFECT: increased reliability of operations of system for automatic correction of video signal and quality of TV broadcasting. 2 cl, 2 dwg
