Consider the following sequential circuit
What are the values of Q0and Q1 after 4 clock cycles if the initial values are ?
(A) 11
(B) 01
(C) 10
(D) 00
Answer: (D)
Explanation: Sequential circuit would produce the following output:
T0 Q0 T1 Q1
1 0 1 0
1 1 1 0
1 0 1 1
1 1 1 1
1 0 1 0
(Q0, Q1 = 0,0), after 4th cycle.
So, option (D) is correct.
