Abstract : A step-by-step procedure is described for designing digital counters having complex, arbitrary sequences. A divide-by-ten up-down counter is then designed to illustrate use of truth tables, 'P' terms, Veitch diagrams, and 'don't care' terms for simplifying the gate functions used to trigger each counter stage. The value of this procedure in circuit analysis as well as for circuit synthesis is then emphasized and illustrated by example. This procedure makes use of fundamental Boolean algebra and minimization techniques. (Author)
