Abstract

L'invention concerne des filtres de signaux électriques de rang élevé. Selon l'invention, on prévoit un filtre (32) du type comprenant deux points de signaux et trois bornes et ayant une fonction de transfert associée; et un moyen synthétiseur (37, 38, 39) pour coupler le filtre au trajet de signaux par une seule borne de jonction (A) pour effectuer le filtrage des signaux transmis par le trajet avec la fonction de transfert du filtre. L'invention s'applique notamment à la télévision en couleur.
