On an eight-square Veitch diagram, a one-
a.
variable term occupies four squares; a two-
variable term occupies two squares; a three-
variable term occupies only one square.
To
plot the expression DPQ+DPQ, work with only
one term at a time.
Start with the first
term on the left (DPQ).
To determine the
b.
proper square, take each variable of the term
(DPQ) and determine which square is common to
all three variables, as follows:
D = squares 3, 4, 7, and 8
P = squares 1,2, 3, and 4
c.
Q = squares 1, 5, 4, and 8
Square 4 is common to all variables of the
term DPQ.
Therefore, the plot for the term
DPQ is square 4, as shown below.
To complete the plot of the expression
DPQ+DPQ, the second term (DPQ) must still be
plotted.
Plot the second term (DPQ) in the
diagram above.
