Abstract

a. Circuit de retard. b. Circuit caractérisé par un circuit de préaccentuation 10 pour accentuer la plage des hautes fréquences d'un signal d'entrée appliqué au composant CTD et un circuit de desac-centuation 30 pour accentuer la région des basses fréquences d'un signal retardé par le composant CTD, le circuit de désaccentuation étant réalisé de façon à compenser la caractéristique du circuit de pré-accentuation et à donner une réponse globale sensiblement plate.
