Das Karnaugh-Veitch-Diagramm (bzw. das Karnaugh-Veitch-Symmetrie-Diagramm, die Karnaugh-Tafel oder der Karnaugh-Plan), kurz KV-Diagramm, KVS-Diagramm oder K-Diagramm (engl. Karnaugh map ), dient der übersichtlichen Darstellung und Vereinfachung Boolescher Funktionen – Umwandlung der disjunktiven Normalform in einen minimalen logischen Ausdruck.

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.

❑ Das KV-Diagramm ( nach Karnaugh und Veith).

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.

Maurice Karnaugh introduced it in 1953 as a refinement of Edward W. Veitch 's 1952 Veitch chart, which was a rediscovery of Allan Marquand 's 1881 logical diagram aka Marquand diagram but with a focus now set on its utility for switching circuits. 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 interactive Karnaugh-Veitch map represents the function y = f(x n,,x 1, x 0).

As you have noticed, with two inputs there are four possible states, as shown in the truth table depicted in Figure 1, which also shows the corresponding Maurice Karnaugh, a telecommunications engineer, developed the Karnaugh map at Bell Labs in 1953 while designing digital logic based telephone switching circuits. The Use of Karnaugh Map. Now that we have developed the Karnaugh map with the aid of Venn diagrams, let’s put it to use. Karnaugh Map Don’t care: An output without affecting the operation of the system. This output may be zero(0) or (1). Don’t care in Karnaugh Map is represented by X. I will explain this in detail in one of my future articles.

This interactive Karnaugh-Veitch map represents the function y = f(x n,,x 1, x 0). You can manually edit this function by clicking on the cells of the map. You can manually edit this function by clicking on the cells of the map.
