Abstract

Un aparato de formacion de imagenes de video incluye un tubo de rayos catodicos (10) que incluye un electrodo de foco (17). Una fuente de una primera senal parabolica (V5) a una frecuencia relacionada a una frecuencia de deflexion, seleccionada de una pluralidad de frecuencias, tiene una amplitud determinada de conformidad con la frecuencia seleccionada. Un circuito de control (Figura 1B) tiene una entrada acoplada a la fuente de la primera senal parabolica (V5) para generar una senal de salida (SALIDA). La senal de salida es para mantener la amplitud de la primera senal parabolica (V5) para la pluralidad de frecuencias de deflexion. Un amplificador (97), que responde a la senal de salida, esta acoplado al electrodo de foco (17) para amplificar la sena parabolica a fin de generar un voltaje de foco dinamico en el electrodo de foco.
