Abstract

LA PRESENTE INVENTION EST DU DOMAINE DE L'ELECTRONIQUE ET ELLE A POUR OBJET UN DISPOSITIF DE CONVERSION DE LA FREQUENCE D'UN SIGNAL EN UN NOMBRE BINAIRE. UN CONVERTISSEUR DE L'INVENTION EST DESTINE A LA CONVERSION RAPIDE ET PRECISE D'UN SIGNAL D'ENTREE DONT LA FREQUENCE VARIE EN FONCTION D'UN PARAMETRE MESURE, EN UN NOMBRE SOUS FORME D'UNITE BINAIRE D'INFORMATION PARALLELE, TRAITABLE PAR CALCULATEUR NUMERIQUE; LE SIGNAL ENTRANT AVANT D'ETRE APPLIQUE AU CONVERTISSEUR 13 EST CONFORME EN 12A ET 13A EN UN TRAIN D'ONDES CARREES POURVU D'UN FRONT; UNE MESURE EST FAITE DURANT UN INTERVALLE DE TEMPS QUI N'A PAS BESOIN D'ETRE SYNCHRONISE AVEC LE SIGNAL D'ENTREE ET QUI EST INDEPENDANT DE SA FREQUENCE, L'INTERVALLE AYANT UNE DUREE FIXE QUI EST UN MULTIPLE PREDETERMINE D'UNE UNITE DE TEMPS DONNE; DANS CET INTERVALLE LES FACTEURS SUIVANTS SONT MESURES DANS UN TRONCON DE TRAIN D'ONDES TOMBANT ENTRE LE DEBUT ET LA FIN DE L'INTERVALLE: NOMBRE D'UNITES DE TEMPS COMPRISES ENTRE LE POINT DE DEPART ET LE FRONT DE LA PREMIERE ONDE COMPLETE DU TRONCON, NOMBRE D'ONDES COMPLETES SITUEES DANS LE TRONCON, NOMBRE D'UNITES DE TEMPS COMPRISES ENTRE LE DERNIER FRONT APPARAISSANT DANS LE TRONCON ET LE POINT DE FIN, LES FACTEURS MESURES SONT APPLIQUES AU CALCULATEUR NUMERIQUE 10 QUI TRADUIT LA FREQUENCE DU SIGNAL ENTRANT EN TERMES BINAIRES A PARTIR D'UNE EQUATION RELIANT LA FREQUENCE A CES FACTEURS; ACCESSOIREMENT LES PARAMETRES CALCULES PAR LE CALCULATEUR 10 SONT SOIT RETRANSFORMES EN VALEURS ANALOGIQUES DANS UN CONVERTISSEUR 16, SOIT LUS DE FACON NUMERIQUE SUR UN AFFICHEUR 15. APPLICATION AUX OPERATIONS DE CONTROLE ET DE TRAITEMENT DES PROCEDES.
