Abstract

La présente invention est du domaine des techniques de l'électronique et elle a pour objet un générateur de fonction, ou caractériseur, électronique. Un générateur de fonction, ou caractériseur, électronique sensible à un contact d'entrée pour produire un signal de sortie qui est une fonction linéiare d'un courant d'entrée variable appliqué à un élément non linéaire 10 produisant le courant d'entrée. Le générateur de fonction est composé de deux branches montées en parallèle avec l'élément non linéaire. La première branche est composée d'une résistance Ra à travers laquelle circule le courant d'entrée pour donner une première tension; la deuxième par une diode 12 ayant un seuil donné monté en série avec une deuxième résistance Rb . Aucun courant d'entrée ne circule dans la deuxième branche tant que la première tension ne dépasse pas le seuil de la diode, après quoi le courant d'entrée circule dans la deuxième résistance pour produire une deuxième tension à travers elle. La première tension est combinée avec une certaine position de la seconde tension pour pdouire le signal de sortie désiré. Applications à la linéarisation des réponses des capteurs de déplacement.The present invention is in the field of electronic techniques and its object is an electronic function generator, or characterizer. An electronic function generator, or characterizer, responsive to an input contact to produce an output signal which is a linear function of a varying input current applied to a non-linear element 10 producing the input current. The function generator is composed of two branches mounted in parallel with the non-linear element. The first branch is composed of a resistor Ra through which the input current flows to give a first voltage; the second by a diode 12 having a given threshold connected in series with a second resistor Rb. No input current flows through the second branch until the first voltage exceeds the threshold of the diode, after which the input current flows through the second resistor to produce a second voltage across it. The first voltage is combined with a certain position of the second voltage to provide the desired output signal. Applications to the linearization of the responses of displacement sensors.
