Abstract

L'invention concerne un appareil électronique, notamment un appareil de champ, comprenant une interface pour communiquer par l'intermédiaire d'une ligne à deux fils. Un convertisseur analogique/numérique (18) est prévu pour convertir un signal de réception (15) modulé en une valeur numérique (19). Le microprocesseur (20) détermine les données (27) transmises sur la base de la séquence temporelle des valeurs numériques (18) et une séquence temporelle de valeurs numériques (38) sur la base des données (36) à transmettre en fonction de chaque procédé de modulation. Un circuit intégré spécifique pour réaliser un modem devient de ce fait superflu.
