Abstract

Un dispositivo de regulación especialmente para receptores de televisión con un tubo electrónico que contiene al menos tres electrodos al cual es conducida una primera tensión de impulsos así como una segunda tensión de impulsos cuyos impulsos individuales tienen una fase variable con respecto a los impulsos correspondientes de la primera tensión del impulsos caracterizada porque de los impulsos de una de las tensiones de impulsos se derivan impulsos de mando y son conducidos al tubo los cuales se diferencian en tal medida en su duración de los impulsos de la otra tensión de impulsos que los pequeños desplazamientos de fase entre las dos tensiones de impulsos no influyen en la tensión de salida del tubo en medida considerable.
