ISRO | ISRO CS 2014 | Question 21

Consider the following sequential circuit What are the values of Q₀and Q₁ after 4 clock cycles if the initial values are 00 ?

(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.
