Karnaugh map or K-map is a map of a function used in a technique used for minimization or simplification of a Boolean expression. It results in less number of logic gates and inputs to be used during the fabrication.

Karnaugh Maps • Algebraic procedures: •Difficult to apply in a systematic way. •Difficult to tell when you have arrived at a minimum solution. • Karnaugh map (K-map) can be used to minimize functions of up to 6 variables. –K-map is directly applied to two-level networks composed of AND and OR gates. •Sum-of-products, (SOP)

Presentation on theme: "THE K-MAP."— Presentation transcript: 2 Karnaugh Map (K-Map) Karnaugh Mapping is used to minimize the number of logic gates that are required in a digital circuit. This will replace Boolean reduction when the circuit is large. Write the Boolean equation in a SOP form first and then place each term on a map.

The article explains the Karnaugh Map (K-Map), a graphical method for simplifying Boolean expressions in digital logic design. It discusses the K-Map’s structure, its application for 2-, 3-, and 4-variable problems, techniques for grouping adjacent cells, and utilizing “don’t care” entries for further simplification of logic functions.

4 Karnaugh Maps (K-Maps) We will use a K-map to simplify the follwing expression. F(x,y,z) = xy’z’ + x’y’z + xz’ + y’z + x’ First we note that there are three variables in the expression F( ), therefore our K-map will have 23=8 cells. Next we decide where each variable will be represented. yz x

The Karnaugh map (K-map) is a visual tool for simplifying Boolean functions, organizing truth table values in a grid based on Gray code. Looping in K-maps involves combining adjacent cells (for SOP) with 1s or (for POS) with 0s to simplify the output expression. Groups of sizes like 2, 4, 8, or 16 are used, with priority given to larger groups.

A K-Map provide a pictorial method of grouping together expression with common factors and therefore eliminating unwanted variables from function. K- Map is extensively used for simplification of boolen expression with up to six variables.
