A “don’t care” condition is a combination of inputs for which the designer doesn’t care what the output is. Bild links oben beginnend, reihenweise von links nach rechts — die gegebene DNF lautet: Auch Bild zeigt eine unkorrekte Gruppenbildung, da die rote Gruppe 3 Einsen umfasst. In the same way, the blue grouping gives the term BC D. Kanraugh Bild sind die 4 Felder jeweils um eine vertikale und horizontale Mittelachse gespiegelt.

Logic circuit simplification (SOP and POS)

Eine Regel besagt aber: A disadvantage is that it is difficult to draw. They are usually indicated on the map with a dash or X. Logical design ee digital computers. Die DNF ist auch gleichzeitig der Minterm. K-Maps for four variables must be depicted as a donut or torus shape. A visualization of the k-map can be considered cylindrical. Archived from the original on Karnaugh map at Wikipedia’s sister projects.

Each cell of the completed Karnaugh map contains a se digit representing the function’s output for that combination of inputs. The example on the right is the same as the example above but with the value of f 1,1,1,1 replaced by a “don’t care”. In Bild bzw. Also contains a short review by Samuel H. Weil sie sich aber auf eine weitere Variable beziehen sind sie nicht mehr so anschaulich.


From Wikipedia, the free encyclopedia. Once the Karnaugh map has been constructed and the adjacent 1s linked by rectangular and square boxes, the algebraic minterms can be found by examining which variables stay the same within each box. Die rote Gruppe reduziert sich zu CD.

Die Achtergruppe reduziert sich zu: The cells are often denoted by a shorthand which describes the logical value of the inputs that the cell covers. All possible horizontal and vertical interconnected blocks can be formed. Taschenbuch der Nachrichtenverarbeitung in German 2 ed. karbaugh

Karnaugh maps are used to facilitate the simplification of Boolean algebra functions. Still more complex maps are needed for 5 variables and more. Auf jede Seite des Diagramms schreibt man je eine Variable — jeweils in normaler und verneinter Form. B is 0 and has ed be negated before it can be included. Cells on the extreme right are actually ‘adjacent’ to those on the far left, in the sense that the corresponding input values only differ by one bit; similarly, so are those at the very top and those at the bottom.

This can be remedied using stencils.

Karnaugh-Veitch Map

The fields at edges on the left and right are adjacent, and the top and bottom are adjacent. Die blaue Vierergruppe vereinfacht sich zu: Here are all the blocks with one field. Bild zeigt eine alternative Gruppenbildung zu Bilddie aber ebenso wie die Gruppenbildung bei Bild leider nicht ganz korrekt ist. The optimal groupings in the example below are marked by the green, red and blue lines, and the red and green groups overlap. Views Read Edit View history.

Content in this edit is translated from the existing German Wikipedia article at [[: Quite diaggramme secondary sources erroneously cite this work as “A logical diagram for n terms” or “On a logical diagram for n terms”. Adjacent 1s in the Karnaugh map represent opportunities to simplify the expression.

Man macht nur keinen Gebrauch davon.

Ansichten Lesen Bearbeiten Versionsgeschichte. Die Bilder bis demonstrieren den logischen Zusammenhang zwischen der Diagrammversion von Veitch und der Version von Karnaugh.

Race hazards are very easy to spot using a Karnaugh map, because a race condition may exist when moving between any pair of adjacent, but disjoint, regions circumscribed on the map. Graphenmethode zur Vereinfachung von Schaltfunktionen”.

Jedoch greift eine weitere Regel: Orten; Gucker, Frank F. Diesen Nachteil kann man allerdings durch die Verwendung von Schablonen verringern. Note that it is acceptable that the green grouping overlaps with the red one. Therefore, A D can be a valid term—it includes cells 12 and 8 at the top, and wraps to the bottom to include cells 10 and 14—as is BDwhich includes the four corners. Dezember um Karnaugh maps also allow easy minimizations of functions whose truth tables include ” karnaufh care ” conditions.
