Abstract

Installation pour détecter des erreurs éventuelles dans une émission de signaux numériques dont la somme est limitée par un codage approprié. Installation caractérisée par un intégrateur analogique avec amplificateur et condensateur, dont la sortie est surveillée par des montages de comparaison qui délivrent un signal d'erreur lorsque sont dépassées des limites de tension, qui sont des representations analogiques de la somme numérique admise pour le signal numérique. Installation applicable à des signaux numériques codés en binaire ou en ternaire.
