Difference between Combinational Circuits and Sequential Circuit.
| COMBINATIONAL CIRCUITS | SEQUENTIAL CIRCUITS |
|---|---|
| The output of the circuit depends on the present state of all the inputs. | The output of the circuit depends on the present state of all the inputs as well as on the past states. |
| There is only one type of input. | There are two types of inputs namely Primary and Secondary Inputs. |
| There are no memory elements present in combinational circuits | Memory elements are required in sequential circuits. |
| Combinational circuits are of only one type. | Sequential circuits are of two types namely Synchronous and Asynchronous. |
| Behaviour is described by Truth Table. | Behaviour is described by State Table. |
| Clock is not required. | Clock is required and present. |
| Example: Parity generators | Example: Parity generators |
