Abstract

Circuit électronique (12) relié à un capteur à excitation variable (24) et comportant : un détecteur d’enveloppe numérique (20) agencé pour acquérir un signal de mesure produit par le capteur en réponse à un signal d’excitation, et comprenant : un convertisseur analogique-numérique (22) agencé pour échantillonner le signal de mesure de manière à produire des points d’échantillon au cours de fenêtres d’observation successives de durée T qui comprennent un nombre de points d’échantillon NS, les points d’échantillon étant espacés d’une période d’échantillonnage TS, la période d’échantillonnage TS et la durée T étant telles que TS = NP.T0 + (NT/NS).T0 et T = NS.TS, où T0 est une période d’excitation du signal d’excitation, où NP, NT et NS sont des entiers naturels non nuls et où NT n’est pas un multiple de NS ; FIGURE DE L’ABREGE : Fig.3
