A function F (A, B,C) defined by three Boolean variables A,BC when expressed as sum of products is given by:
\(F = \bar A\bar B\bar C + \bar AB\bar C + A\bar B\bar C\)
where A̅, B̅ and C̅ are the complements. The POS form of function is1
F = Σm (0, 2, 4)
2
F = Σm (1, 3, 5, 6, 7)
3
F = ΠM (0, 2, 4)
4
F = ΠM (1, 3, 5, 6, 7)
