Direction: A PLA realization is shown below

  1. f1 (x2, x1, x0) =?
    1. x2 –x0 + x1 x0
    2. x2 x0 + x1 –x2
    3. x2 ⊕ x0
    4. x2 ⊙ x0
Correct Option: C

From figure

f1 = x0 x2 + x0 x1 x2 + x0x2
f1 (x2, x1, x0) = x0 x2 + x2 x0 (from K-map)
= x2 ⊕ x0

Hence alternative (C) is the correct choice.
