Abstract

L'invention concerne la transmission de données. Le dispositif de l'invention est destiné à transmettre des données asynchrones organisées par caractère sur une voie de transmission synchrone, avec une cadence qui peut dépasser la cadence synchrone. Dans ce but, un circuit tampon d'entrée 8 appartenant à l'émetteur supprime occasionnellement des bits de fin en fonction de l'écart entre la cadence synchrone et la cadence asynchrone. Un circuit tampon de sortie 49 appartenant au récepteur rétablit les bits de fin manquants. Application à la téléinformatique.
