To plot the expression A+B on a Veitch

b.

1 and 2

diagram, start with

the first term on

the

c.

2 and 4

left and mark the squares assigned to

d.

3 and 4

the variable (A) of that term as shown below.

Next, on the same diagram, mark the squares

assigned to the variable (B) of the second

term, as shown below.

Note that one square of variable B had been

marked from the plotting of variable A.

The

expression A+B has been plotted on a four-

square Veitch diagram, and the completed

diagram is shown below.

Plot the expression A+B on the Veitch diagram
