Abstract

L'invention concerne un procédé de mesure du taux d'erreurs de bits dans un système de multiplexage par répartition dans le temps. Selon ce procédé qui est basé sur la comparaison d'un premier signal arrivant à la partie d'entrée Et à un second signal de consigne produit dans un générateur QZG, dans un comparateur VGL, et qui contient un compteur FZ d'erreurs de bits intervenant lors de la comparaison, un dispositif de mémoire d'erreurs FS et un système MU de commutation de la plage de mesure et un circuit de synchronisation SYNG, la durée de l'intervalle de temps suivant un intervalle de temps d'interrogation est réglée en fonction du nombre d'erreurs de bits dans l'intervalle précédent, puis avec raccourcissement ou prolongement du temps de mesure. Application notamment aux systèmes de contrôle de transmissions PCM.The invention relates to a method for measuring the bit error rate in a time division multiplexing system. According to this method which is based on the comparison of a first signal arriving at the input part Et with a second reference signal produced in a generator QZG, in a comparator VGL, and which contains a bit error counter FZ intervening during the comparison, an error memory device FS and a measuring range switching system MU and a synchronization circuit SYNG, the duration of the time interval following a polling time interval is set depending on the number of bit errors in the previous interval, then with shortening or extension of the measurement time. Application in particular to PCM transmission control systems.
