The transfer function of the communication channel in a mud pulse telemetry system is determined by sending a known signal through the channel and spectral analysis of the received signal. The known signal may be a chirp signal or a stepped frequency signal. Based on the determined transfer function, operating parameters of the pulser are adjusted.

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.
