Abstract

Procédé de suppression du bruit dans une ligne de transmission (1) consistant à extraire un signal de mode commun depuis des signaux d'arrivée. La sortie de l'amplificateur différentiel (2) mis en corrélation avec le signal de mode commun est intégrée (10) et l'équilibre du signal dans la ligne de transmission est réglé sur la base de l'intégration.
