Abstract

L'INVENTION CONCERNE UN CIRCUIT DE CONTROLE DE LA TENSION DE SORTIE D'UN CAPTEUR MAGNETIQUE. ELLE SE RAPPORTE A UN CIRCUIT DE DETECTION DE DONNEES CONVENABLES DE SORTIE A PARTIR DE SIGNAUX D'ENTREE QUI PEUVENT AVOIR UNE FAIBLE AMPLITUDE OU UNE AMPLITUDE ELEVEE ET QUI PEUVENT COMPRENDRE DES IMPULSIONS DE DEPASSEMENT D'AMPLITUDE IMPORTANTE. LE CIRCUIT COMPREND DEUX COMPARATEURS 52, 54 QUI COMPARENT LE SIGNAL DU CAPTEUR A DES TENSIONS DE CONSIGNE DECALEES DE PART ET D'AUTRE DU NIVEAU MOYEN, ET UNE PORTE 72 COMPARE LE SIGNAL D'UN COMPARATEUR AU SIGNAL DE L'AUTRE APRES RETARD. APPLICATION AUX APPAREILS DE TRI D'ENVELOPPES CODEES.
