Minimize following
F(x,y,w, z) = (0,2,4,6,12,14)
Above is a common format of representing the K-map problems. The numbers 0, 2, 4,
6, 12, 14 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.
The K-map for 4 variables is plotted above. You will notice the column and rows for 11 and 10 are inter-changed. This is done to allow only one variable to change across adjacent cells. This adjustment in columns allows in minimization of logic mapped into tables.
Any adjacent 1, 2, 4 or 8 cells can be grouped to find a minimized logic value.
