Title
(EN)
DIGITAL PERIOD DIVIDER
(FR)
DIVISEUR DE PÉRIODE NUMÉRIQUE
Abstract:
(EN)
A system may have a digital period divider generating an output signal that is proportional to an angle defined by a rotational input signal and an interval measurement unit determining an interval time of an interval defined by succeeding pulses of the input output signal. In an enhancement, the system may also have a missing pulse detector which is operable to compare a current interval with a parameter to determine whether a pulse is missing in the input signal.
(FR)
Un système selon l'invention peut comporter un diviseur de période numérique générant un signal de sortie qui est proportionnel à un angle défini par un signal d'entrée de rotation et une unité de mesure d'intervalle déterminant un temps d'intervalle ayant un intervalle défini par des impulsions successives du signal de sortie fourni en entrée. Dans une amélioration, le système peut également comprendre un détecteur d'impulsion manquante qui est conçu pour comparer un intervalle courant à un paramètre pour déterminer si une impulsion est manquante dans le signal d'entrée.
