Abstract

L'INVENTION CONCERNE LES CIRCUITS DE TRAITEMENT DE SIGNAUX ELECTRIQUES. UNE SOURCE D'IMPULSIONS D'ENTREE 11 ATTAQUE UNE BASCULE BISTABLE 12 QUI EST ASSOCIEE A UN INTEGRATEUR A DOUBLE PENTE 13 ET A UN COMPARATEUR 14. GRACE A CETTE CONFIGURATION, IL APPARAIT EN SORTIE DE LA BASCULE 12 DES SIGNAUX PERIODIQUES DONT LA DUREE EST EGALE A UNE FRACTION PRECISE DE LA PERIODE DES IMPULSIONS D'ENTREE, INDEPENDAMMENT DU RAPPORT CYCLIQUE DE CES IMPULSIONS. APPLICATION AUX DISPOSITIFS D'ALLUMAGE POUR MOTEURS A COMBUSTION INTERNE.
