Abstract

Système modulateur-démodulateur à canaux multiples, destiné à recevoir d'un appareil associé de traitement de données des codes de demande de combinaison de canaux. Un dispositif mémorise la combinaison présente des canaux et un dispositif compare cette combinaison à celle demandée par l'appareil de traitement de données afin de provoquer le passage de l'ancienne combinaison à la nouvelle combinaison demandée. Domaine d'application: systèmes modulateurs-démodulateurs.A multi-channel modulator-demodulator system for receiving channel combination request codes from an associated data processing apparatus. A device stores the present combination of channels and a device compares this combination with that requested by the data processing apparatus in order to cause the change from the old combination to the new requested combination. Field of application: modulator-demodulator systems.
