Which is the correct truth-table for J-K flip-flop?

a.

b.

c.

d.

ANSWER:

Explanation:

J-K Flipflop has an ability to overcome the drawbacks of S-R flipflops .

When both the inputs of JK flipflop are zero, the output is Qn while when both the inputs are 1, the output is the complement of Qn i.e (Q

n).

When the inputs are in the form of '0' , '1' & '1','0' respectively, then the outputs are generated in accordance to the J input value; i.e, outputs are '0' & '1' respectively for both the conditions.
