Abstract

Dispositif de compression. Les sons reçus en 12 sur le microphone sont enregistrés en 10 sur l'enregistreur. L'arrêt du dispositif 10 se fait automatiquement lorsqu'il y a détection d'une séquence de bits sortant du modulateur 20 correspondant à la détection d'un silence. Lorsque la séquence du << silence>> disparaît l'enregistrement reprend. Application aux machines à dicter.
