Counters

Counters. Introduction: Counters. Counters are circuits that cycle through a specified number of states. Two types of counters: synchronous (parallel) counters asynchronous (ripple) counters Ripple counters allow some flip-flop outputs to be used as a source of clock for other flip-flops.
