Karnaugh Map. Using Boolean algebra to simplify Boolean expressions can be difficult and may lead to solutions which, though they appear minimal, are not. The Karnaugh map provides a simple and straight-forward method of minimising boolean expressions which represent combinational logic circuits.

Diagramele Karnaugh, numite și hărți Karnaugh, au fost inventate în 1950 de Maurice Karnaugh, un inginer în telecomunicații de la Laboratoarele Bell pentru a facilita minimizarea expresiilor algebrice booleene. În mod normal, pentru minimizarea acestor expresii este nevoie de calcule complicate, folosind formule și iterații, pe când Diagramele Karnaugh sunt mult mai simplu și mai rapid de utilizat pentru că folosesc capabilitățile creierului uman de recunoaștere a formelor

In combinatorial logic minimization, a device known as a Karnaugh map is frequently used. It is similar to a truth table, but the various variables are represented along two axes and are arranged in such a way that only one input bit changes in going from one square to an adjacent square. It is also known as a Veitch diagram, K-map, or KV-map. Karnaugh-Map for Three Inputs The K-map for two inputs can be extended to three inputs by combining the third input either in the horizontal or vertical direction with the input already placed there. Here we do that horizontally, and the third variable C is combined with B, as it is shown in Figure 2.

This is an online Karnaugh map generator that makes a kmap, shows you how to group the terms, shows the simplified Boolean equation, and draws the circuit for up to 6 variables. It also handles Don't cares. The Quine-McCluskey solver can be used for up to 6 variables if you prefer that. Select the number of variables, then choose SOP (Sum of Karnaugh-diagrammet Grafisk metod för minimering ”för hand” av mindre booleska funktioner (för upp till sex variabler) Maurice Karnaugh ( The Map for Synthesis of Combinational Logic Circuits, AIEE, Nov. 1953 ) Karnaugh-diagram.

An example Karnaugh map. This image actually shows two Karnaugh maps: for the function ƒ, using minterms (colored rectangles) and for its complement, using maxterms (gray rectangles). In the image, E() signifies a sum of minterms, denoted in the article as ∑.

Das Karnaugh-Veitch-Diagramm , kurz KV-Diagramm, KVS-Diagramm oder K-Diagramm , dient der übersichtlichen Darstellung und Vereinfachung Boolescher Funktionen in einen minimalen logischen Ausdruck.
