Question

What are D type flip flops used for? And what is the difference between JK and T flip flop?

Answer 1

Answer:

Explanation:

The data or D-type Flip Flop can be built using a pair of back-to-back SR latches and connecting an inverter (NOT Gate) between the S and the R inputs to allow for a single D (data) input. The basic D flip flop circuit can be improved further by adding a second SR flip-flop to its output that is activated on the complementary clock signal to produce a “Master-Slave D flip-flop” device.

The difference between a D-type latch and a D-type flip-flop is that a latch does not have a clock signal to change state whereas a flip-flop always does. The D flip-flop is an edge triggered device which transfers input data to Q on clock rising or falling edge.
