Abstract

L'invention concerne un appareil destiné à recevoir des informations, en évitant les perturbations dues à des harmoniques d'un signal permanent. Les données sont transmises sous forme de paires d'impulsions représentant chacune un bit La durée des impulsions, l'intervalle qui les sépare et la fréquence porteuse sont choisis de manière telle que les harmoniques d'un signal permanent sur la ligne de transmission ne puissent apporter aucune perturbation la réception des données. L'invention s'applique notamment à la transmission des données sur les lignes de transport d'énergie.
