Abstract

Un réseau de découplage, qui sert à bloquer des signaux de transmission à haute fréquence sur des lignes d'alimentation, comprend un filtre ayant un premier élément en séries (10) destiné à être connecté à une ligne d'alimentation, un second élément en séries (11) destiné à être connecté à la même ligne d'alimentation ou à une autre ligne d'alimentation et un élément en dérivation (12) connecté entre les éléments en séries et à travers les deux lignes d'alimentation. L'élément en dérivation agit comme un court-circuit pour les signaux à haute fréquence, bloquant ainsi le passage des signaux de communication à travers le réseau. Dans un mode de réalisation, un circuit processeur de signal (13) est couplé inductivement aux éléments en séries pour permettre le traitement des signaux de communication provenant de l'autorité de distribution et des consommateurs. Le réseau empêche le passage des signaux de communication directement de l'autorité de distribution vers les consommateurs ou vice versa.
