Abstract

Sistema transmisor de mensajes que comprende, en combinación, una estación transmisora dotada de un transmisor, un cierto número de producciones de frecuencias, procedimientos selectivos de comunicación que interconectan dichos elementos de producción de frecuencias con el transmisor mismo para modular la producción obtenida incluyendo a su vez los procedimientos de conmutación medios para seleccionar combinaciones de frecuencias que correspondan a los mensajes que han de transmitirse y una estación receptora dotada de un receptor, procedimientos de filtraje conectados a dicho receptor para separar el conjunto de frecuencias transmisoras, procedimientos de reproducción de los mensajes y sistemas en conexión con dichos filtros para controlar de modo automático dichos procedimientos de reproducción de los mensajes que resulten por las combinaciones de frecuencias recibidas y reproducción de los mensajes recibidos en el transmisor.
