Abstract
ANALYSE DU CONTENU HARMONIQUE D'UN SIGNAL PERIODIQUE. SELON UN ASPECT DE LA MISE EN OEUVRE DE L'INVENTION, ON PRELEVE DES ECHANTILLONS TOUT AU LONG D'UN GRAND NOMBRE DE PERIODES D'UNE FORME D'ONDE A ANALYSER A UNE CADENCE QUI EST UN MULTIPLE ENTIER DE LA FREQUENCE DE CETTE FORME D'ONDE, ON EFFECTUE LA SOMME DE CHAQUE ECHANTILLON D'UNE PERIODE ET DES ECHANTILLONS CORRESPONDANT DES AUTRES PERIODES ET ON APPLIQUE UNE TRANSFORMATION DE FOURIER AUX SOMMES OBTENUES POUR MESURER L'UNE AU MOINS DES COMPOSANTES DE LA FORME D'ONDE ANALYSEE. APPLICATION AUX RESEAUX DE DISTRIBUTION D'ENERGIE ELECTRIQUE.
