Abstract

L'invention concerne un dispositif de restitution d'un signal binaire modulant une onde porteuse, cette onde porteuse modulée étant préalablement filtrée. Il comporte un circuit détecteur d'enveloppe, 2, qui fournit un signal représentant la partie positive de l'enveloppe de l'onde modulée et filtrée, un comparateur, 7, qui compare ce signal d'enveloppe à un autre signal obtenu par transposition et intégration du signal d'enveloppe; cette transposition et cette intégration sont obtenues par les circuits de transpositions 3 et 4. Applications aux démodulateurs d'ondes modulées par un signal binaire.
