The Answer:
The correct answer is option 'B' - The D input is HIGH and the clock transitions from LOW to HIGH.
Explanation:
A positive edge-triggered D flip-flop is a sequential logic circuit that transfers data (stored in the D input) to the output (Q) only when a positive edge of the clock signal is detected. Here's a detailed explanation of why option 'B' is the correct answer:
Positive Edge-Triggered D Flip-Flop:
A positive edge-triggered D flip-flop consists of a D input, a clock input, and two outputs - Q (the stored value) and Q' (the complement of Q). The flip-flop transfers the value of the D input to the output (Q) only when there is a positive transition (LOW to HIGH) on the clock input.
Explanation of Options:
a) The D input is HIGH and the clock transitions from HIGH to LOW:
In this case, the flip-flop will not store a 1 because the clock transition is from HIGH to LOW, which is a negative edge. The flip-flop only responds to positive edges of the clock.
b) The D input is HIGH and the clock transitions from LOW to HIGH:
This is the correct option. When the D input is HIGH and the clock transitions from LOW to HIGH, the flip-flop will store a 1. The positive edge of the clock triggers the transfer of the D input to the output.
c) The D input is HIGH and the clock is LOW:
In this scenario, the flip-flop will not store a 1 because there is no clock transition. The clock must transition from LOW to HIGH to trigger the transfer of data.
d) The D input is HIGH and the clock is HIGH:
Similar to option 'c', the flip-flop will not store a 1 because there is no clock transition. The clock must change from LOW to HIGH for the flip-flop to transfer the data.
Conclusion:
In a positive edge-triggered D flip-flop, the stored value will be 1 only when the D input is HIGH and the clock transitions from LOW to HIGH. This behavior allows the flip-flop to capture and store data at the positive edges of the clock signal, making it a fundamental building block in digital systems for synchronous operations.
