Abstract

Una disposición de circuito para generar una señal que consiste en una onda portadora modulada en ancho de impulso cuya profundidad de modulación representa una forma de onda de señal preseleccionada como función del tiempo, caracterizada porque la disposición de circuito comprende un primer contador, una primera entrada para recibir una primera señal de sincronismo con la ayuda de la cual se inicia periodicamente el funcionamiento del primer contador, una segunda entrada para recibir una segunda señal de sincronismo, siendo contados por el primer contador los impulsos de dicha segunda señal de sincronismo, y circuito secuencial para detectar consecutivamente cómputos preseleccionados del primer contador, cuyo circuito secuencial genera la onda portador modulada en ancho de impulso.
