Abstract

Circuito de barrido de trama, en modo conmutado, que funciona a partir de la señal de retorno de barrido de línea, suministrada por un devanado secundario del transformador de línea de un receptor de video-frecuencia, caracterizado porque el desviador vertical está conectado en serie con una resistencia de medida y con un condensador de enlace, cuyo valor es suficientemente elevado para que la tensión en los bornes del conjunto así formado conserve la misma polaridad, cualquiera que sea el sentido de la corriente que atraviesa el desviador vertical, comportandose este conjunto entonces tanto como generador, tanto como receptor, y estando conectado a un circuito generador de una señal en dientes de sierra, a partir de la señal de retorno del barrido de línea, monodireccional en tensión y bidireccional en corriente, accionado por un circuito de mando, sincronizado a la frecuencia de línea por un circuito de sincronización.
