The switching function
f (A, B, C) = (A + B′ + C) (A′ + B′ + C) (A + B′ + C′)
can also be written as—
-
- Σ m (2, 3, 6)
- Σ m (0, 1, 4, 5, 7)
- Σ m (1, 2, 5, 6, 7)
- Σ m (0, 2, 4, 6)
Correct Option: B
Question given in maxterm or POS form and options are given in minterm form. So, first we have to convert POS into SOP form.
(maxterm)′ = minterm
Leaving 2, 6, 3 rest are maxterm decimal equivalent
π M (A + B′ + C) (A′ + B′ + C) (A + B′ + C′)
= Σ m (0, 1, 4, 5, 7)
Hence alternative (B) is the correct answer.
