Abstract

L'INVENTION CONCERNE LES APPAREILS D'ENREGISTREMENT DE SIGNAUX ACOUSTIQUES SOUS FORME NUMERIQUE. ELLE SE RAPPORTE A UN APPAREIL DE TRAITEMENT DE SIGNAUX ACOUSTIQUES DESTINES A ETRE NUMERISES ET ENREGISTRES SUR UNE PISTE UNIQUE D'UN SUPPORT D'ENREGISTREMENT. LE CIRCUIT DE L'APPAREIL ASSURE LA CORRECTION DE BLOCS ERRONES DE MOTS DE DONNEES PAR MISE EN OEUVRE D'UN CODE DE PARITE ET DE MOTS DE DONNEES D'AUTRES BLOCS DE DONNEES, LORSQUE LA COMPARAISON ENTRE UN CODE DE VERIFICATION D'ERREURS CREEES ET UN CODE DE VERIFICATION D'ERREURS RECUES INDIQUE UNE DIFFERENCE. APPLICATION AUX MAGNETOPHONES NUMERIQUES POUR USAGE PROFESSIONNEL.
