Table 2: Two variable K-map

The square’s also called cells have specific numbers. See table below:

The zero (0) and one (1) coordinate on the variables means that A and have a value of 0 and 1 and so is
variable B. When labeling the cells (squares), start with a column and then row, for example the top
most columns are AB or (00). This also means that this cell is at the intersection of column A and B .
This can also be written as cell number (00). The same applies to the rest of the cells. It is important to
know that the cells represent the input combinations where the value of F (output of the function) will be
written for minimizing purposes.

7.4 Two variable Karnaugh maps
The two- variables K - map has four possible states and each variable is represented by half the total
number of cells/squares (see example below). The cells are represented by numbers, which can be used
to quicken the process of minimization, for example 00 is (0), 01 is 1, 10 is 2 and 11 is 3.

B A 0 1

0 00 10

1 01 11
