Abstract

Circuit de filtrage à branches multiples interconnectées par des commutateurs actionnés cycliquement. Il comporte un multivibrateur monostable 16 permettant de faire varier les coefficients d'utilisation des commutateurs S1 à S4 de commande des filtres passe-bas constitués par une résistance commune R1 et des condensateurs C1 , C2 , C3 et C4 . Domaine d'application : filtres passe-bandes.
