Abstract

Chronométreur de bande numérique électronique. Il utilise un format de huit chiffres, dont cinq affichés; l'un des trois autres devient le chiffre de plus faible poids, dont le module est modifié pour présenter le taux de division correct aux impulsions tachymétriques incidentes. Le compteur engendre des chiffres séquentiels apparaissant chacun sur un conducteur de signal d'horloge choisi, moyennant quoi les huit chiffres sont transmis en utilisant quatre fils pour le code binaire pour un fil pour la sélection de chaque chiffre à afficher, ce qui offre, comme avantage un multiplexage par partage de temps du signal de sortie du chronométreur. Affichage de la position instantanée et du temps de déplacement de la bande dans un magnétoscope.
