4 variable K-map, Example to Minimize following equation. 

3 var KMAP example

Above is a common format of representing the K-map problems. The numbers 0,2,5,7,8,11,13,15 are the location of cells in the 4-var k-map table. Discussed below is a 4 variable K– map with 1 and 0 values. assigned to cells.

Any adjacent 1, 2, 4 or 8 cells can be grouped to find a minimized logic value. The minimization equation is shown below. With reference to the table above the cells under the dotted box’s can be combined to come up with following reduced equation.
F = w’y’ + yw .. Final Answer.

Examples Next. Four variables K-map (truth table and K-map plot).

  1. F(x,y,w, z) = (0,1,2,3,4,6,11,14)
  2. F(x,y,w, z) = (0,2,4,6,12,14)
  3. F(x,y,w, z) = (0,2,5,7,8,11,13,15)
