Abstract

Un dispositivo para modular una señal de televisión en color compuesta, caracterizado porque está provisto de un filtro de separación para separar la señal de luminancia y la señal de crominancia, un modulador de frecuencia para la modulación de frecuencia de una señal portadora con la señal de luminancia, un circuito mezclador que está acoplado con el modulador de frecuencia para recibir la señal portadora modulada y con el filtro de separación para recibir la señal de crominancia, un filtro que está acoplado a la salida del circuito mezclador para extraer la señal subportadora, y un modulador de ancho de impulsos, acoplado con dicho filtro y con la salida del modulador de frecuencia, para la modulación del ancho de impulsos de la señal portadora modulada dependiendo de la señal subportadora.
