Solution:

What is the addition of the binary number 110001+101011=?

01011100

01011110

11011101

01010110

Solution:

If (A+B)(A+C)=1, B'C'+BC=0 and AB=0 , find A,B,C

A=1,B=0,C=0

A=0,B=1,C=0

A=1,B=1,C=1

A=1,B-1,C=0

A=1,B=0,C=1

Solution:

Which of these sets of logic gates are known as universal gates?

XOR, NAND, OR

OR, NOT, XOR

NOR, NAND, XNOR

NOR, NAND

Solution:

Which method(s) will be preferable to solve a 8 variable boolean expression ?

Karnough Map

Quine McCluskey

Both a and b

None of the above

Solution:

What is the expression of Sum in a full adder:-

ABC+AB'C+AB'C'

A'B'C+A'BC'+AB'C'

A XNOR B XNOR C

A XOR B XOR C

BOTH 1 AND 4

BOTH 2 AND 4

Solution:

Which of these options are correct?

Minterms are the implicants in POS form,

Maxterms are the implicants in POS form.

Maxterms are the implicants in SOP form.

Solution:

Determine the values of A,B,C, and D such that they make sum term A'+B+C'+D = 0?

A = 1, B = 0 , C = 0 , D = 0

A = 1 , B = 0 , C = 1, D = 0

A = 0, B = 1, C = 0, D = 0

A = 1, B = 1, C = 0, D = 0

Solution:
