Abstract
L'INVENTION CONCERNE LES CIRCUITS DE TEMPORISATION DE TYPE NUMERIQUE. UN CIRCUIT DE TEMPORISATION NUMERIQUE COMPREND UN SEUL COMPTEUR REVERSIBLE 15 ET DES ELEMENTS LOGIQUES DE COMMANDE ASSOCIES. ON ASSURE L'IMMUNITE AUX TROUS, INTERRUPTIONS, ETC., DE L'IMPULSION D'ENTREE EN COMMANDANT LE COMPTEUR DE FACON QU'IL COMPTE EN SENS CROISSANT PENDANT UN INTERVALLE PREDETERMINE, INDEPENDAMMENT DE LA PRESENCE OU DE L'ABSENCE DE L'IMPULSION D'ENTREE. LORSQUE L'IMPULSION D'ENTREE A DISPARU PENDANT UN INTERVALLE INTEGRE PREDETERMINE, ON COMMANDE LE COMPTEUR DE FACON QU'IL CONTINUE A COMPTER EN SENS DECROISSANT JUSQU'A CE QU'IL RETOURNE A L'ETAT INITIAL, INDEPENDAMMENT DE LA PRESENCE OU DE L'ABSENCE DE L'IMPULSION D'ENTREE. APPLICATION AUX SYSTEMES DE SIGNALISATION DE TELECOMMUNICATIONS.
