Abstract

Le procédé et le dispositif servent à la démodulation d'un signal d'entrée (E1) reçu qui comprend un signal de données (D) modulé. Le signal d'entrée (E1) est mélangé à un signal de comparaison (V) pour donner un signal de fréquence intermédiaire (ZF1) à partir duquel est produit un signal de fréquence intermédiaire (ZF2) traité. Dans une unité de contrôle (6), le signal de données (D) est récupéré à partir du signal de fréquence intermédiaire (ZF2), traité en particulier au moyen d'une exploration. Le signal de comparaison (V) utilisé pour le mélange et en particulier également un signal d'exploration (A1) utilisé pour l'exploration, ainsi qu'un signal d'émission (S1, S2) à la base du signal d'entrée (E1) sont dérivés du signal de synchronisation (T) prévu pour fournir la synchronisation à l'unité de contrôle 6. De ce fait, une seule horloge (16) est nécessaire.
