Select the appropriate answer for each question.
1. Based on the below state diagram and having input X and output Y, which of the following
statements is correct?
a. When X=0, the state C will change to D and Y = 0.
b. When X = 0, the state B will change to C and Y = 1
c. When X = 1, the state B will remain unchanged and Y = 1.
d. When X = 1, the state A will change to B and Y = 0.
2. To implement the Boolean function F = A + B + C we can use a 3-to-8 decoder and
connect:
a. 3 different lines from its output to an OR gate
b. 4 different lines from its output to an OR gate
c. 5 different lines from its output to an OR gate
d. 6 different lines from its output to an OR gate
e. 7 different lines from its output to an OR gate
3. Two Tâ„¢ Flip-Flops, A and B, are used to implement the shown state diagram. To go from
state "AB = 00" to "AB=11" we need:
a. TA=0, TB = 0
b. TA=0, TB = 1
c. TA=1, TB = 0
d. TA=1, TB = 1
4. The correct state diagram for the circuit shown below is:
a)
b)
c)
d) None of above
