Abstract

L'invention concerne un appareil de détection d'un signal de porteuse seule. Un régénérateur 28 reçoit une série de données d'enseignement comportant un signal de porteuse seule 11 et comprend un dispositif d'échantillonnage traitant lesdites données. Un appareil détecteur du signal de porteuse seule comprend un dispositif pour fournir une séquence d'arcs tangents (ACK/BCK) à partir des échantillons dérivés durant le signal de porteuse seule et un dispositif pour tester lesdits arcs tangents afin de déterminer la présence dudit signal de porteuse 91,92,93 93 et 94. Application à des signaux de canaux de communication de données.
