Abstract

Ce générateur de fonctions pour la production d'une fonction à caractéristique quadratique comporte une entrée 1 pour un signal d'entrée et une sorte 3 sur laquelle apparaît ladite fonction. Il comprend un circuit générateur 4 qui produit une onde triangulaire à une fréquence prédéterminée, un comparateur A6 pour produire un train d'impulsions, la largeur de ces impulsions étant déterminée par l'amplitude du signal d'entrée et leur fréquence par la fréquence de l'onde triangulaire. Un contact électronique V5 est commandé par le train d'impulsions et délivre des impulsions dont la largeur est déterminée par celle des impulsions du train et dont l'amplitude est fixée par l'amplitude du signal d'entrée. Les impulsions sont appliquées à un circuit de traitement d'impulsions A8 qui les évalue et délivre un signal de sortie qui est proportionnel au carré de l'amplitude du signal d'entrée.
