SYNTHESIS OF FLIP-FLOP SYSTEMS.

A system of general rules is developed for constructing structural diagrams of various flip-flop systems with nine possible types of control. This system is then used to devise a universal and ultimately simple method of synthesizing uniphase and symmetrical and asymmetrical paraphase flip-flop systems. The method requires the execution of several formal rules and takes up minimum design internal states of the system, but yields structures with counterdrive encoding. The method provides various versions of minimum structure circuits of all possible types of control simultaneously, and is especially effective in synthesizing multiple-input, logically complex systems. A program for the automated design of such systems is developed on the basis of this method.
