Abstract

SISTEMA DE CONTROL AUTOMATICO DE SEÑALES DE VIDEO EN RECEPTORES DE TELEVISION. INCLUYE UN CAMINO DE CONTROL CON UN DETECTOR PARA PROPORCIONAR UNA TENSION DE CONTROL DE SALIDA INDICATIVA DE UNA CANTIDAD DE INFORMACION DE ALTA FRECUENCIA QUE INCLUYE COMPONENTES DE ACENTUACION PRESENTES EN LA SEÑAL DE VIDEO. EL DETECTOR ESTA PRECEDIDO POR UN AMPLIFICADOR SELECTIVO DE FRECUENCIA QUE INCLUYE UNA RED DE FILTRO ASOCIADA PARA ESTABLECER LA RESPUESTA DE FRECUENCIA DEL SISTEMA. EL AMPLIFICADOR Y EL FILTRO ESTAN DISPUESTOS DE MANERA QUE EL AMPLIFICADOR ACOPLA UN INTERVALO DADO DE SEÑALES DE VIDEO DE ALTA FRECUENCIA AL DETECTOR, PERO ATENUA SIGNIFICATIVAMENTE COMPONENTES DE VIDEO DE BAJA FRECUENCIA, PARTICULARMENTE COMPONENTES DE CORRIENTE CONTINUA, EN LA SEÑAL SUMINISTRADA AL DETECTOR.
