Abstract

Ce récepteur est pourvu d'un décodeur de code de ligne et d'un convertisseur numérique-analogique. Pour diminuer l'audibilité des salves d'erreurs, ce récepteur est également pourvu d'un détecteur de violation qui constate si le signal reçu présente des divergences par rapport au code de ligne, ainsi que d'un générateur d'impulsions. Chaque fois que le détecteur de violation constate que le signal reçu présente des divergences par rapport au code de ligne, le signal de sortie du décodeur de code de ligne n'est plus amené au convertisseur numérique-analogique mais est remplacé par le signal de sortie du générateur impulsions. Application aux télécommunications numériques et aux enregistrements magnétiques.
