Title (EN) GENERALISED CONNECTION NETWORK
(FR) RESEAU DE CONNEXION GENERALISE
Abstract:
(EN) A generalised connection network comprising a first and second sub-network (2, 4) interconnected by a branching circuit (6) having N inputs I1 to I4 and N outputs 01 to 04. The branching circuit (6) has N, two-state branching elements (10) interconnected so as to be able to replicate a signal coupled to any one of the inputs I1 to I4 to each of up to N outputs 01 to 04. The cyclic connection scheme provided by an additional two-state switch permits a net reduction in the total number of two-state switches necessary to form a generalised connection network.
(FR) Un réseau de connexion généralisé comprenant un premier et un second sous-réseau (2, 4) interconnecté par un circuit de branchement (6) possédant N entrées I1 à I4 et N sorties 01 à 04. Le circuit de branchement (6) possède N éléments de branchement à deux états (10) interconnectés pour pouvoir reproduire un signal couplé à l'une des entrées I1 à I4 vers chacune des N sorties 01 à 04. Le schéma de connexion cyclique fourni par un commutateur deux-états supplémentaire permet une réduction nette du nombre total de commutateurs deux-états nécessaires pour former un réseau de connexion généralisé.
