what is the Output F

Question

Comments

It is Xnor.

---

$F(A,B) = A'B'A' + A'BB' + AB'A' + ABB$

$F(A,B)=A'B' + AB$

it is expression for XNOR gate

---

Y=A'B' + AB

It means XNOR of two inputs.

So the correct answer is A) XNOR

---

I have solved in this way

I0 = A'B'A = 0

I1 = A'BB' = 0

I2 = AB'A' = 0

l3 = ABB =AB

So im getting And Operation

Did anything wrong in this

Answer 1

Characteristic equation of MUX is 

Now S1 = A & S0 = B 

I0=D0= $\widehat{A}$

I1= D1=$\widehat{B}$

I2= D2=$\widehat{A}$

I3=D3= B

Putting them in equation we get 

$A′B′A′+A′BB′+AB′A′+ABB$

=>$F(A,B)=A′B′+AB$

It is exnor
