Monotone Functions in Sequential Circuits

This paper is concerned with the problem of realizing an arbitrary syndconous or asynchronous sequential machine using only monotone AMR (or decreasing) switching functions. It has been found that h ion always exist, that in the asynchronous case only nomal fundamental mode flow tables are considered. Univesl state assignmments resulting in monotone inceasing (or next-state funtions are characterized using the concept of an (i,j) completely separating system.
