Abstract

La fonction de transfert d'un canal de communication dans un système télémétrique par impulsions dans la boue est déterminée par envoi d'un signal connu à travers le canal et analyse spectrale du signal reçu. Le signal connu peut être un signal chirp ou un signal de fréquence par palier. On règle les paramètres de fonctionnement du générateur d'impulsions en fonction de la fonction de transfert déterminée.
