Abstract

Oscillateur délivrant des impulsions rectangulaires à fréquence de sortie variable, à l'aide d'une bascule de Schmitt commandée par un élément RC. Une source de courant constant délivre le courant IK nécessaires à la charge du condensateur CT . Un circuit image de courant T2 assure en outre l'égalité des courants de charge et de décharge du condensateur.
