Abstract

L'influence perturbatrice des impulsions d'horloge inévitablement émises par un convertisseur dans un système à transpondeur passif peut assurer une fonction utile si l'on utilise dans un convertisseur CC-CC des impulsions d'horloge commandées par un cristal de quartz au lieu du multivibrateur flou commandé par une horloge RC. Si l'on commande la fréquence du cristal de quartz à l'aide de diviseurs, on peut utiliser les impulsions d'horloge du convertisseur comme modulation FSK et transmettre ainsi des données du transpondeur ou de l'étiquette au lecteur.
