Abstract
En vue de la mise sous forme numérique d'une valeur analogique à entrer, un générateur d'impulsions 1 électromécanique est monté à l'amont du système, les impulsions de ce générateur pouvant être comptées dans le compteur 9. Le contenu numérique du compteur peut être converti sous forme analogique par convertisseur numérique-analogique 11, valeur analogique dont l'importance peut être modifiée en fonction de la position angulaire de l'élément de commande 5 du générateur d'impulsions 1. Un dispositif 16 commandé par le convertisseur numérique-analogique 11 est monté à l'aval de la sortie analogique 14 de ce convertisseur.With a view to the digital form of an analog value to be entered, an electromechanical pulse generator 1 is mounted upstream of the system, the pulses of this generator being able to be counted in the counter 9. The digital content of the counter can be converted into analog form by digital-to-analog converter 11, an analog value whose importance can be changed as a function of the angular position of the control element 5 of the pulse generator 1. A device 16 controlled by the digital converter analog 11 is mounted downstream of the analog output 14 of this converter.
