What is the main difference between sequential logic and combinational logic?
What is the main difference between sequential logic and combinational logic?
- Combinational logic depends on the present and past inputs, while sequential logic depends only on the present input.
- Sequential logic has no memory, while combinational logic has memory.
- Combinational logic uses finite-state machines, while sequential logic does not.
- Sequential logic depends on the present and past inputs, while combinational logic depends only on the present input. (correct)
