25.
Consider the circuit shown below of 2 : 1 MUX is given by the function g = ac + bc

Then f is :
X ⊕ Y
XY + EXY
XE + XY
none of these
Answer: Option
Explanation:

Since g = ac + bc

i.e. when c = 0, g = b and c = 1, g = a

Now we evaluate

f = (E)(X) + (0)(X) = EX

f = (X)(Y) + (EX)(Y) = XY + EXY.
