Abstract

Le dispositif selon l'invention se distingue en ce qu'il engendre une troisième condition logique de contrôle et il comporte un émetteur de ligne différentielle et balancée à double source de courant et un récepteur constitué par deux amplificateurs opérationnels ayant à l'entrée un circuit de polarisation, et à la sortie une fonction ET, la troisième condition logique étant obtenue par la non-commutation desdites sources de courant et étant appliqué sur les caractères écho.
