Product term explained
In Boolean logic, a product term is a conjunction of literals, where each literal iseither a variable or its negation.
Examples
Examples of product terms include:
A\wedge(\negB)\wedge(\negC)
Origin
The terminology comes from the similarity of ANDto multiplication as in the ring structure of Boolean rings.
Minterms
For a boolean function of
variables
, a product term in which each of the
variables appears
once (in either its complemented or uncomplemented form) is called a
minterm. Thus, a
minterm is a logical expression of
n variables that employs only the
complement operator and the
conjunction operator.
