Consider the sequential circuit shown in the figure, where both flip-flops used are positive edge-triggered D flip-flops. \"5\" The number of states in the state transition diagram of this circuit that have a transition back to the same state on some value of \”in\” is ______ . Note – This was Numerical Type question.

(A)

2

(B)

3

(C)

4

(D)

None



Answer: (A)

Explanation:

State Table : \"Selection_028\" \"gate_cs2018_dl_2\" Transition back to the same state means self loop, they are asking number of self loop states. Number of self loop states are 2 ( which are 00 and 11). Option (A) is CORRECT.
