Question #69497
9. a) Explain the working of D-flip flop. How does it differ from a D-latch?
Expert's answer
Solution: D-flip flop is an electronic device that can be used to store one bit of information. The D flip flop is used to capture the logic level which is present on the Data line at the moment of a positive edge of the signal at the clock pin (or negative edge if the clock input is active low) and keeps this level for one cycle. If the data on the D line changes state before next positive edge of the signal at the clock pin, the output, Q is not changed, unlike in the D-latch where Q follows the change of D until the CLK turns low (when CLK is low they keep the previous D state)
