Abstract

Mejoras en sistemas de comunicación radioeléctrica caracterizada por utilizar medios de transmitir comunicación sensible comprendiendo la impresión de señales audibles de comunicación de transmitir impulsos de una banda de frecuencia más baja que la banda de frecuencia de dichas señales, y aplicar la comunicación impresionada a la transmisión de dichos impulsos a velocidad reducida conmensurable con dicha banda de frecuencia más baja para modular los impulsos transmitidos en correspondencia con dicha comunicación.Improvements in radioelectric communication systems characterized by using means of transmitting sensitive communication comprising the impression of audible communication signals of transmitting pulses of a frequency band lower than the frequency band of said signals, and applying the impressed communication to the transmission of said pulses at a reduced speed commensurate with said lower frequency band to modulate the pulses transmitted in correspondence with said communication.
