Abstract
L'invention concerne les appareils d'affichage graphique. Elle se rapporte à un appareil qui crée des vecteurs par transmission d'impulsions d'horloge à un compteur-décompteur 10 qui commande, par l'intermédiaire d'un convertisseur, la tension de déviation de l'axe X d'un dispositif d'affichage. Les impulsions d'horloge parviennent aussi par une porte 14 à un second compteur-décompteur 11 qui commande la déviation suivant l'autre axe d'affichage par l'intermédiaire d'un autre convertisseur. La porte 14 est commandée par le débordement d'un accumulateur 18 d'un signal représentatif de la pente voulue pour le vecteur. L'appareil permet. la formation de courbes circulaires. Application aux appareils d'affichage de vecteurs, de courbes et de caractères.
