METHODS AND SYSTEMS WITH DOWNHOLE SYNCHRONIZATION BASED ON A DIRECT DIGITAL SYNTHESIZER (DDS)
A downhole system includes a first module having a transmitter that transmits at least one sync control signal. The system also includes a second module having a sync module with a direct digital synthesizer (DDS). The sync module analyzes the at least one sync control signal to identify at least on...

| description | A downhole system includes a first module having a transmitter that transmits at least one sync control signal. The system also includes a second module having a sync module with a direct digital synthesizer (DDS). The sync module analyzes the at least one sync control signal to identify at least one of a sync frequency and a sync phase. The DDS adjusts a local receiver clock based on the identified at least one of a sync frequency and a sync phase.
L'invention concerne un système de fond de trou comprenant un premier module comportant un émetteur qui émet au moins un signal de commande de synchronisation. Le système comprend également un second module comportant un module de synchronisation équipé d'un synthétiseur numérique direct (DDS). Le module de synchronisation analyse ledit signal de commande de synchronisation pour identifier une fréquence de synchronisation et/ou une phase de synchronisation. Le DDS règle une horloge de réception locale sur la base d'une fréquence de synchronisation et/ou d'une phase de synchronisation identifiées. |
