Comparison between Combinational circuit and Sequential circuit
Combinational Circuit
- Just logic gates are used for circuit. Memory elements are not used.
- Output of any instant is depending on only that instant input condition.
- There is no delay between input and output.(excluding propagation delay)
- Circuit does not contain memory element so design of circuit is easy.
- Require more hardware compare to Sequential circuit
- Due to more hardware cost is more.
Sequential Circuit
- Logic gates and Memory elements both are used for circuit.
- Output of any instant is depending on that instant input condition. And It also depends of previous condition of output.
- There is delay between input and output.(excluding propagation delay)
- Circuit contain memory element so design of circuit is difficult.
- Require less hardware compare to Combinational circuit
- Due to less hardware cost is less.
