Abstract

Perfeccionamientos en osciladores de sincronismo vertical para señales de televisión, sincronizables por los impulsos de cambio de imagen de una señal de televisión que se toma de una etapa de impulsos, que consta de un amplificador realimentado cuya salida está enlazada con un condensador de carga del que se puede tomar una tensión alterna en forma de diente de sierra de frecuencia vertical para la desviación de la imagen de un receptor de televisión, por cuanto que el condensador de carga se carga durante la ida de imagen y se descarga durante el retorno de imagen por el amplificador, caracterizados porque la salida de la etapa de impulsos, de la que pueden tomarse los impulsos de cambio de imagen de la señal de televisión, esté enlazada con la salida del amplificador para la sincronización del oscilador vertical.
