MINIMIZATION USING FOUR VARIABLE KARNAUGH MAP

The K-

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 = x’y’ + x’w’ + zw’
