Title (EN) DEVICE FOR COMPENSATION OF TRANSFER FUNCTIONS
(FR) DISPOSITIF DE COMPENSATION DE FONCTIONS DE TRANSFERT
Abstract: front page image
(EN)Device for compensation of electric transfer functions of electric or electronic sensors (G), detectors, instruments or four-poles. According to the invention, the signal from the unit (G) to be compensated is connected to a differential amplifier (D) with a feed-back network (Z) having a transfer function that is as similar as possible to the transfer function to be compensated. Hereby the compensating device has a transfer function that approximately is inverse to the transfer function of said sensor (G). The signal that the sensor senses and that is distorted by the nonlinear transfer function of the sensor is then restored. The feedback network can either be passive or consist of electrically controllable active filters.
(FR)Dispositif de compensation de fonctions de transfert electrique de capteurs (G), detecteurs, instruments ou quadripoles electriques ou electroniques. Le signal provenant de l"unite (G) a compenser est connecte a un amplificateur differentiel (D) avec un reseau de reaction (Z) ayant une fonction de transfert qui est aussi semblable que possible a la fonction de transfert a compenser. Ainsi, le dispositif de compensation possede une fonction de transfert qui est approximativement inverse de la fonction de transfert du capteur (G). Le signal que le capteur capte et qui est deforme par la fonction de transfert non lineaire du capteur est ensuite restaure. Le reseau de reaction peut etre passif ou bien consister en filtres actifs pouvant etre commandes electriquement.
