Product of Sums form, or
POS form, is a method of writing
logical equations. In this
form, the equation consists of multiple
terms which are all
AND'd together. In turn, each of these terms consists of one or more
variables which are all
OR'd together. Example:
_ _ _ _ _ _
F = (A + B + C) · (A + B + C) · (A + B + C) · (A + B + C) · (A + B + C)
Here each of the
terms are within
parenthesis, and consist of
variables
OR'd together. Each of the terms, then, is
AND'd together.
