What is the probability of output generation when the inputs are '1' & '0' respectively in S-R clocked flipflop?

a. 1,1 & output remains undefined because outputs try to become '1'

b. 1,0 & flip-flop is reset

c. 0,1 & flip-flop is set

d. 0,0 & output remains unchanged

ANSWER: 0,1 & flip-flop is set

Explanation:

Set & Reset actions of S-R clocked flipflop are performed only on the basis of a clock pulse. So, when

S=0 & R =0, outputs are 1,1 ( output remains unchanged)

S=0 & R = 1, outputs are 1,0 ( Reset action of flipflop)

S= 1 & R=0, outputs are 0,1 ( Set action of flipflop)

S= 1 & R=1, outputs are 0,0 (output remains undefined since they ought to be 1)
