Abstract

Perfeccionamientos en generadores de impulsos de supresión de retroceso para receptores, del tipo que comprenden, un aparatos de deflexión sincronizado con una fuente de señales de sincronización que inician una transmisión en los impulsos de supresión, cuyo generador de impulsos de supresión comprende una fuente de energía de servicio, caracterizados porque se dispone en cada generador de un dispositivo de almacenamiento de energía que tiene una constante de tiempo predeterminada; un dispositivo de conmutación acoplado a la fuente de señales de sincronización, a la fuente de energía para cambiar el acoplamiento del dispositivo de almacenamiento de energía a la fuente de energía de servicio en sincronismo con las señales de sincronización; una primera fuente de potencial de referencia; un primer dispositivo comparador, que tiene una primera entrada acoplada a la primera fuente de potencial de referencia, y una segunda entrada acoplada al dispositivo de almacenamiento de energía, acoplándoseel primer dispositivo comparador a la salida del generador de impulsos de supresión en un instante después de la señal de sincronización, estando determinado el retardo después de la señal de sincronización por la constante de tiempo.
