Abstract
Dispositif de transmission numérique comportant un récepteur à démodulation cohérente réalisée directement en hyperfréquence.
Son émetteur utilise un oscillateur synthétise (1A) dont la référence (24) est fournie par le rythme (H) des données (P, Q).
Son récepteur utilise, comme oscillateur de demodulation (13A), un sythétiseur fonctionnellement identique au premier (1A), et dont la référence (23) est fournie par le rythme récupéré (H, 36) des données reçues.
