Abstract

L'invention porte sur un procédé de communication à travers la terre, qui comprend les étapes consistant, à un premier emplacement, à utiliser un train d'impulsions numériques pour générer un train d'impulsions de balayage qui commande la fréquence d'un champ magnétique, et à un second emplacement, à détecter le champ magnétique et à produire un signal à une fréquence qui dépend de la fréquence du train d'impulsions de balayage, et à extraire une copie du train d'impulsions numériques à partir du signal.
