Difference Between Synchronous Counters and Asynchronous Counters in Tabular Form
| SNO. | Synchronous Counters | Asynchronous Counters |
| 1. | Simultaneous clock signal is given to all the flip-flops connected in synchronous counters. | Clock is provided to first flip-flop and the output of first flip-flop acts as clock second flip-flop and so on. |
| 2. | Speed is fast as no clock delay is provided to flip-flops. | Speed is slow as compared to synchronous counters as clock signal is delayed for other flip-flops except the first one. |
| 3. | Circuit is complex or complicated as number of states increases. | Circuit ls simple. |
| 4. | Cost is more as additional circuitry is required. | Cost is less as compared to synchronous counters. |
| 5. | Synchronous counter is known as parallel counter. | Asynchronous counter is known as serial counter |
| 6. | ![]() | ![]() |
