Abstract
L'invention concerne les techniques de calcul numérique. Le dispositif numérique faisant l'objet de l'invention est caractérisé notamment en ce qu'il comprend un dédoubleur de fréquence 21, trois circuits NON 11 à 13, sept circuits ET 14 à 20, et que le discriminateur 8 d'intervalles de temps a une sortie d'informations reliée aux premières entrées respectives des premier, deuxième, troisième et quatrième circuits ET, et reliées en outre, par l'intermédiaire du premier circuit NON, à une première entrée du cinquième circuit ET. L'invention peut être utilisée en particulier dans les systèmes de traitement préliminaire d'informations appliquées à des capteurs de paramètres de processus technologiques, notamment pour déterminer sous une forme numérique la température d'un acier liquide mesurée à l'aide de thermocouples à immersion.
