Abstract

Dispositif de mesure de la pente moyenne d'une courbe représentative d'un phénomène en évolution, courbe mise sous la forme d'une grandeur électrique variant en fonction du temps. Comprend un échantillonneur, échantillonnant le signal électrique à étudier, un convertisseur analogique numérique et une série de registre à décalage et une unité de calcul effectuant le calcul de la pente suivant la formule P (pente) = DELTA V / DELTA T où DELTA V représente la variation de l'amplitude des échantillons correspondant à l'intervalle de temps DELTA T choisi par la mesure. Application à l'étude de tout phénomène physique ou chimique en évolution.
