Question-2

a)  Verify if, P.(P’ + Q’) = (P=>Q) using truth table.

Answer : 

P Q P(bar) Q(bar) P(bar)+Q(bar) P[P(bar)+Q(bar)] P=>Q
0 0 1 1 1 0 0
0 1 1 0 1 0 0
1 0 0 1 1 1 1
1 1 0 0 0 0 0

 

b)  What is connective?

Answer : 

Connectives are the operators that are used to combine one or more propositions.

or

A logical connective (also called a logical operator) is a logical constant used to connect two or more formulas to make an expression.  

c)  Give truth table proof for De Morgan’s law.

Answer : 

According to De’ Morgans Law

(A.B)(bar) = A(bar)+B(bar)

A B A(bar) B(Bar) (A.B)(bar) A(bar)+B(bar)
0 0 1 1 1 1
0 1 1 0 1 1
1 0 0 1 1 1
1 1 0 0 0 0

 

d)  Prove the complementary law with the help of truth table.

Answer : 

Complementary Law is also known as De’ Morgans Law.

A B A(bar) B(Bar) (A.B)(bar) A(bar)+B(bar)
0 0 1 1 1 1
0 1 1 0 1 1
1 0 0 1 1 1
1 1 0 0 0 0

 

e)  Prove x + x’y = x + y using Boolean algebraic method.

Answer : 

x + x’y = x + y

(x + x’)x + y = x + y          [dempotence Law]

1.x + y = x + y

x + y = x + y
