Chapter 12.2, Problem 10E

Another way to find a Boolean expression that represents a Boolean function is to form a Boolean product of Boolean sums of literals.

Exercises 711 are concerned with representations of this kind.

10.Show that a oo1ean function can be represented as a oo1ean product of maxterms. This representation called the product of sum is expansion or conjunctive normal form of the function. [Hint: Include one max-term in this product

for each combination of the variables where the function has the va1ue 0.]
