A positive edge-triggered D flip-flop will store a 1 when ________(a) The D input is HIGH and the clock transitions from HIGH to LOW(b) The D input is HIGH and the clock transitions from LOW to HIGH(c) The D input is HIGH and the clock is LOW(d) The D input is HIGH and the clock is HIGHI have been asked this question in my homework.The origin of the question is D Flip Flop in chapter Flip-Flops of Digital Circuits

Answer» CORRECT answer is (b) The D input is HIGH and the clock transitions from LOW to HIGH

The best I can explain: A positive edge-triggered D flip-flop will STORE a 1 when the D input is HIGH and the clock transitions from LOW to HIGH. While a negative edge-triggered D flip-flop will store a 0 when the D input is HIGH and the clock transitions from HIGH to LOW.
