Which of the following is NOT a characteristic of a sequential logic circuit?.
- A.Uses clock signals
- B.Has memory elements
- C.Output depends on past inputs
- D.Output depends only on current inputs
Model answer
What a good answer should say
- Output depends only on current inputs
Explanation
Why this works
Define both: a sequential logic circuit uses clock signals and memory elements, and its output depends on both current inputs and stored past inputs. Identify key difference: the output dependence on past inputs.
Explain when each applies: the option stating output depends only on current inputs describes a combinational circuit, not a sequential one. Conclude: therefore this option is not a characteristic of sequential logic.
