Topological Solution of Bilateral Switching Networks

A method is described for synthesizing bilateral switching networks using a topological solution that does not employ algebraic or linear graph techniques. Using the eye as a pattern detector, one may trace an optimum path directly on the truth table from the input to the one or more desired outputs. This method overcomes many of the difficulties that have been encountered with relay contact logic, and at the same time helps the logician seek a planar symmetrical solution thaat is so desirable for monolithic circuits composed of MOS (metal-oxide semiconductor) devices.
