Exam-style question
Try this first
If a clock signal is omitted from a sequential circuit, the circuit will:.
- A.operate synchronously
- B.operate asynchronously
- C.operate faster
- D.operate slower
Model answer
What a good answer should say
- operate asynchronously
Explanation
Why this works
Formula/rule: Without a clock, sequential elements have no common timing reference and will change state whenever their inputs change. Substitution: The absence of a clock removes the edge trigger.
Working: Inputs can change at any time, causing outputs to change unpredictably and potentially leading to race conditions. Answer: operate asynchronously.
Units/conclusion: The circuit loses synchronous control and behaves as an asynchronous system.
