Abstract

Receptor de televisión en que el tamaño de la porción de la pantalla del tubo de imagen efectivamente usada para la reproducción tiene una razón de cuadratura que difiere de la razón de cuadratura determinada por la señal de televisión entrantecaracterizado por el hecho de que la disposición de circuito presente en el receptor para producir una corriente deflectora diente de sierra de por lo menos un haz electrónico en la dirección de la desviación de línea del tubo de imagen está proporcionada de modo que el periodo de retorno y el valor de cresta a cresta de la corriente deflectora diente de sierra están adaptados a la razón de cuadratura de la porción de l apantalla efectivamente usada para la reproduccióny que el receptor comprende medios par producir una tensión que permite que el haz o haces electrónicos sean suprimidos por lo menos durante el mencionado período de retorno.
