Abstract

L'invention concerne un procédé d'envoi de signal de commande, un procédé de réception de signal de commande et un dispositif, se rapportant au domaine des terminaux intelligents. Un signal de commande d'une extrémité d'envoi est porté sur un signal sonore et le signal sonore est modulé et, ensuite, envoyé à une extrémité de réception ; le son est démodulé au niveau d'une extrémité de réception de telle sorte qu'un signal de commande correspondant soit obtenu. Ainsi, l'invention concerne un mode d'envoi de signal de commande et un mode de réception de signal de commande capables, dans un environnement de test de fréquence radio, de mettre en œuvre une commande de signal sur un dispositif sous test au moyen d'un son. Une interférence de signal de commande sur un signal de test est évitée et l'efficacité de test de fréquence radio est ainsi améliorée.
