Abstract

Sistema de radiodifusión por canales múltiples que lleva una estación transmisora, teniendo una antena omnidireccional situada en un punto ventajoso para el área que se quiere servir, medios para transmitir por dicha antena en una frecuencia portadora, una serie de canales cada uno representado por un tren de impulsos entrelazados en sucesión con los impulsos de los otros canales, y medios para dar a los impulsos de uno de dichos canales una característica distintiva e identificadora para sincronizar el radioreceptor a la sucesión de transmisión de dichos canales.
