Question 2 |
A Boolean digital circuit is composed using two 4-input multiplexers (M1 and M2)
and one 2-input multiplexer (M3) as shown in the figure. X0-X7 are the inputs of
the multiplexers M1 and M2 and could be connected to either 0 or 1. The select
lines of the multiplexers are connected to Boolean variables A, B and C as shown.
Which one of the following set of values of (X0, X1, X2, X3, X4, X5, X6, X7) will realise the Boolean function \bar{A}+\bar{A}\cdot \bar{C}+A\cdot \bar{B}\cdot C ?

Question 5 Explanation:
There are 5 questions to complete.
Sir, Please mention the a,b,c value of question 2.
Hi Ashutosh,
Here, value of a,b,c are not required. You can write the truth table based on above circuit. Then find the answer based on truth table. See the solution provided.
Question 5, Please update the answer from 4 minimum gate to 3 minimum gate.
Hi Ashutosh,
Thank you for your suggestion. We have updated the answer from 4 to 3.
Q13 answer will be B…
Update it
Thank You akki yadav, We have updated the answer suggested by you.
Update Question No. 46. The options should be Q1Q0 instead of Q0Q1
Update Q56 as B instead of C
Thank You Sowmya Sri,
We have updated the answer.
Question number 42 in the Digital Logic subject is not part of Boolean Algebra, it should be present in the propositional logic section on Discrete Mathematics.
in Q-228 option A,C are same
Dear praveen kumar,
We have updated option C.
In question 206 option D is correct, but there is typo in option d displayed. It should be staring with wxy’
