Abstract
Two synchronizing flip-flops synchronize the transitions of a slow clock to a fast clock. The state of a version of the synchronized slow clock is stored by a last-state flip-flop that is clocked on an edge of the fast clock. The last-state flip-flop is compared by logic to a version of the synchronized slow clock to produce a pulse with a width determined by either a phase of the fast clock or a cycle of the fast clock.
