The synthesis of combinatorial logic functions using ULM 3 universal circuit elements

This paper briefly considers existing information on universallogic- modules which may be used for the realization of functions of n¿3 independent input variables (`ULM.3¿), and their circuit realizations, and selects two candidates, f4 and f5, as preferable choices for practical adoption. The synthesis of arbitrary n-variable functions using these candidates is then pursued, including the utilization of symmetries in the functions being synthesized.
