Abstract

La présente invention est du domaine des transmissions numériques synchrones. Elle a pour objet un dispositif de contrôle de la qualité d'un signal de transmission numérique en bande de base à intervalle de temps unitaire constant comportant un autocorrélateur à coïncidence de signe effectuant la corrélation des polarités de deux versions du signal reçu retardées l'une par rapport à l'autre d'un multiple entier de l'intervalle de temps unitaire. Elle a un domaine d'application analogue au diagramme de l'oeil.
