It is a way of minimizing the Boolean functions using diagrams which are made up
of squares. By minimization we imply a function with minimum number of terms and
each term with lowest number of literals.
Following k-map for 2-5 variables are discussed in this section:
First write the Truth Table for 2 variables x and y. Once we know all the values
in table its easier to plot the k-map.
2 variable K– map plot below : - Each element (0-3) from above table is plotted in
k-map below. Var x is horizontal row and y is vertical column. There intersection
denotes output function element. 2 var KMAP below.
