On an eight-square Veitch diagram, a one-
variable term occupies four squares; a two-
variable term occupies two squares; a three-
variable term occupies only one square.
one term at a time.
Start with the first
term on the left (DPQ).
To determine the
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
Q = squares 1, 5, 4, and 8
Square 4 is common to all variables of the
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
Plot the second term (DPQ) in the
