Abstract

L'invention concerne un montage pour la détermination du sens de rotation d'un tachymètre numérique. Dans ce montage, aux entrées E1, E2 duquel arrivent deux suites d'impulsions de cadence qui traversent des organes NON I1 à I4, des organes de retardement V1, V2, des organes ET Ul à U8 et des organes OU 01, 02 pour sortir à des sorties A1, A2, on obtient quatre types d'impulsions possibles dont trois sont envoyés selon des combinaisons respectivement différentes aux entrées des portes ET réparties en deux groupes U1, U3, U5, U7; U2, U4, U6, U8 en sorte qu'une impulsion de sortie est délivrée par l'une des portes ET lors de l'arrivée d'un flanc d'une impulsion de l'une des deux suites d'impulsions de cadence à l'une des deux sortes A1, A2 selon le sens de rotation du tachymètre. Application notamment aux systèmes d'entraînement de bandes d'appareils magnétiques à bande.
