Abstract
Récepteur (200) comprenant une commande automatique de la fréquence qui détermine la fréquence d'un signal reçu (408) et qui calcule une erreur de fréquence (410) à partir du signal reçu. L'erreur de fréquence est utilisée pour calculer un facteur de correction dont on se sert pour régler la fréquence (412) d'un oscillateur (308) en réponse à une erreur déterminée.
