Abstract

A magnetic bubble domain junction which permits the information in two separate propagation paths A and C to cross over each other without deleterious effects. The crossover junction includes a merge device Mc for joining the paths into a common path and an active transfer switch Tc between the common path and an output path B. The information on the two paths is arranged to become interleaved at the merge and to be separated at the active transfer switch, so that do mains from A pass to B whereas domains from C pass to D. Arrangements are described for crossing over more than two propagation paths by using information properly timed and spaced, or using a multiple junction network. <IMAGE>
