Introduction to Karnaugh Map


Karnaugh Maps - Rules of Simplification



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 general 2n cells.
    That is if n = 1, a group will contain two 1's since 21 = 2.
    If n = 2, a group will contain four 1's since 22 = 4.
  • Each group should be as large as possible.
  • Each cell containing a one must be in at least one group.
  • Groups may overlap.
  • Groups may wrap around the table. The leftmost cell in a row may be grouped with the rightmost cell and the top cell in a column may be grouped with the bottom cell.
  • There should be as few groups as possible, as long as this does not contradict any of the previous rules.

Summmary:

  1. No zeros allowed.
  2. No diagonals.
  3. Only power of 2 number of cells in each group.
  4. Groups should be as large as possible.
  5. Every one must be in at least one group.
  6. Overlapping allowed.
  7. Wrap around allowed.
  8. Fewest number of groups possible.

A story about Prof. Karnaugh


Maurice Karnaugh


Maurice Karnaugh (born October 4, 1924, in New York City) is an American physicist known for the Karnaugh map used in Boolean algebra.
Karnaugh studied mathematics and physics at City College of New York (1944–48) and transferred to Yale University to complete his B.Sc. (1949), M.Sc. (1950) and Ph.D. in physics with a thesis on The Theory of Magnetic Resonance and Lambda-Type Doubling in Nitric-Oxide (1952).
Karnaugh worked at Bell Labs (1952–66), developing the Karnaugh map (1954) as well as patents for PCM encoding[1]and magnetic logic circuits and coding.[2][3] He later worked at IBM's Federal Systems Division in Gaithersburg (1966–70) and at the IBM Thomas J. Watson Research Center (1970–89), studying multistage interconnection networks.[4]
Karnaugh was elected an IEEE Fellow in 1976, and held an adjunct position at Polytechnic University of New York at the Westchester campus from 1980 to 1999.

He has been married to the former Linn Blank Weil since 1970. He has two grown sons, Robert and Paul, from his first marriage.
