For a given number of variables, there are a

b.

given number of

possible minterms.

For

three

c.

variables, there are eight possible

minterms.

g.

For.

example, for the variables A, B,

and C,

h.

the truth

table and minterms are shown

below.

In order to construct a VEITCH diagram, it is

necessary to know the number of possible minterms.

A Veitch diagrams is a block of squares on which

an expression is plotted.

A simplified expression

is then extracted from the plotted squares.

Determine the number of variables in an expression

and use this number as a power of two.

For

example, the expression JG+JF+JGF+F has three

variables.

J, G, and F.

To find how many

possible minterms there are for this expression,
