http://vlsigyan.com/johnson-counter-verilog-code/ WebExplanation: Synchronous counters are the counters being triggered in the presence of a clock pulse. Since all of the clock inputs are connected through a single clock pulse in ring shift and johnson counters. So, both are synchronous counters. WebSynchronous binary counters have a regular pattern and can be constructed with complementing flip-flops and gates. The C inputs of all flip-flops are connected to a common clock. The counter is enabled with the count enable input. If the enable input is 0 all J and K inputs are equal to 0 and the clock does not change the state of the counter. arti icu rumah sakit
