Electrical Engineering XYZ MCQs
A D-flip-flop is said to be transparent in case the output:
- Follows clock
- Is LOW
- Follows input
- Is HIGH
Correct answer: 3. Follows input
Explanation:
- A D-flip-flop is a type of digital storage element in digital circuits.
- “Transparent” in the context of a flip-flop means that the input signal is directly reflected at the output whenever the clock signal is active.
- The term “follows input” means that the output of the flip-flop mirrors the state of the input whenever the clock signal is active.
- In contrast, a non-transparent flip-flop would only capture the input when the clock signal transitions, and the output would not necessarily follow the input at all times.
Therefore, in the case of a transparent D-flip-flop, the output follows the input when the clock signal is active.
