Abstract
L'invention concerne un procédé et un dispositif de division de fréquences audibles supprimant les distorsions de raccordement du signal de sortie. Le procedé de l'invention consiste à éliminer les distorsions de raccordement en détectant les passages à zéro dans le même sens du signal vocal et en raccordant les tronçons du signal de sortie sur ces passages à zéro. Application à la rééducation de personnes sourdes profondes ayant des restes auditifs dans les graves.
