Veitch diagrams could be
identified
with just one term, such as A, GF, LTD, etc.
It is often necessary to use more than one
term to describe a plot.
In these cases, the
terms must be joined with OR signs.
For
example, expression ABC+ABC+ABC+ABC is
plotted on the Veitch diagram below.

term AB.
To describe the plot above in simplified
form, join the two terms (AC and AB) with an
OR sign.
Expression ABC+ABC+ABC+ABC is
described in simplified form as AC+AB.
