Fecha de publicación: 26/08/2016 Fuente: Wipo "digitalization" A method and apparatus for single signal, multiplechannel digital information transfer through waves withtime slot allocation. The apparatus consists of one or moretransmitting devices and one or more receiving devices.Multiple source signals are each allocated a unique timeslot between successive synchronization waves Digitalsignals from each source are converted to analog informationwaves synthesized from a combination of a fundamentalfrequency wave and a finite number of its harmonics. Thetotal signal, which consists of successive synchronization waves interspersed with information waves for each signalsource, each within its allocated time slot, is transmittedto the receivers. Each receiving device extracts thefundamental frequency and harmonic components through theuse of narrow bandpass, high Q filters for each information wave in its time slot and uses the known algorithm toreproduce the input digital signals. One or more of theharmonic components may be used for transmitting a referencecalibration signal.
