Abstract
A.BRANCHEMENT POUR EXPLOITER DES SIGNAUX ELECTRIQUES DONT L'AMPLITUDE ET LA FREQUENCE VARIENT EN FONCTION D'UNE VITESSE DE ROTATION. B.BRANCHEMENT CARACTERISE EN CE QUE POUR PERMETTRE LA REGULATION DES AMPLITUDES DES SIGNAUX, CES SIGNAUX SONT AMENES A L'INTREE INVERSANTE D'UN COMPARATEUR PAR L'INTERMEDIAIRE D'UNE RESISTANCE, QUI CONSTITUE EN COOPERATION AVEC LA SECTION EMETTEUR-COLLECTEUR D'UN TRANSISTOR UNE RESISTANCE VARIABLE DE DIVISION, LA SORTIE DU COMPARATEUR ETANT RELIEE PAR L'INTERMEDIAIRE D'UN CONDENSATEUR DE DIFFERENCIATION AVEC UN ORGANE TEMPORISE CONSTITUE D'UN CONDENSATEUR D'ACCUMULATION ET D'UNE RESISTANCE DE DECHARGE, AUX BORNES DUQUEL S'APPLIQUE UNE TENSION CROISSANT PROPORTIONNELLEMENT A LA FREQUENCE ET ABAISSANT ALORS LA RESISTANCE INTERNE DU TRANSISTOR. C.L'INVENTION S'APPLIQUE NOTAMMENT AUX MOTEURS D'AUTOMOBILES.
