Abstract
Procédé de transmission de signaux par ondes électromagnétiques modulées par impulsions. Il consiste à former un signal polyvalent de commande SS dont deux valeurs correspondent aux signes de la différence entre un signal d'entrée et un signal suiveur et une troisième au non-dépassement d'un seuil prédéterminé de cette différence, à intégrer les deux premières valeurs et à maintenir l'intégrale de la troisième au niveau présent pour obtenir le signal de sortie, à déclencher la remise à zéro du signal suiveur en fonction du passage par zéro de la courbe de variation du signal d'entrée et à transmettre un signal correspondant de remise à zéro à la réception et à l'utiliser dans cette dernière pour la remise à zéro du signal de sortie. Application en particulier à la transmission de signaux de mesure de courant ou de tension de forte intensité, par exemple par des fibres optiques.
