Abstract
A method for realizing, and a structure for implementing a switching network employing 2.times.2 switches. The network is dilated in that none of the 2.times.2 switches concurrently carry an active signal. The method for realizing such a network alters a given non-dilated network by replacing each 2.times.2 switch in the non-dilated network with a dual rail switch having a pair of 2.times.2 interconnected switches, and by replacing each link in the non-dilated network with a pair links. The final output of the dilated network is obtained by adding a combiner final stage which combines the pairs of signals to form output signals that parallel the output signals of the given non-dilated network.
