Karnaugh Map (K-map) (pronounced car-no map) 3-Variables K-map 4-Variables K-map Map Labeling . The coordinates of the cells in a K-map are the input value combinations from the truth table. There are a number of common ways to label a K-map. The two most common methods are numerically and by variables and their complements. There are advantages to both. Regardless of which way …

This Presentation will give a detailed explanation about the K Map with examples. There is a two-dimensional map that can be used for up to four variables, and a three-dimensional map for up to six variables. 13. Referring to the map above, the two adjacent 1’s are grouped together. Through inspection it can be seen that variable B has its true and false form within the group. This
simple as they can be usually implemented using a standard gate; K-maps for 5 variables become too complicated as they are three dimensional). Computer programs are usually used for 5 variables and above. Karnaugh maps are a method of designing logic systems. Figure 1: A two variable Karnaugh Map.

A generalization of the k-map method is to introduce variables into the k-map squares. These are called entered variable k-maps . This is useful for functions of large numbers of variabes, and can generally provide a clear way of representing Boolean functions.
As an example, let’s simplify the 3 bit K map above. Notice the four three variable expressions reduce down to three two variable expressions. This is a substantial savings in circuitry, and the equation will do exactly the same thing as the original unsimplified expression from the truth table.
• An n-variable K-map has 2n cells with each cell corresponding to an n-variable truth table value. • K-map cells are labeled with the corresponding truth-table row. • K-map cells are arranged such that adjacent cells correspond to truth rows that differ in only one bit position (logical adjacency). Karnaugh Maps (K-maps) •If m i is a minterm of f, then place a 1 in cell i of the K-map The Karnaugh map uses the following rules for the simplification of expressions by grouping together adjacent cells containing ones. Groups may not include any cell containing a zero. Groups may be horizontal or vertical, but not diagonal. Groups must contain 1, 2, 4, 8, or in
