### Worksheet No. 4

No. 1 Simplify the following Karnaugh maps and write down the Boolean equation for every map.

 0 0 1 0 1 1 0 0

 1 1 0 0 1 0 1 1

 1 0 0 0 0 0 1 0

 0 1 0 0 1 0 1 1 1 0 0 1 0 1 1 0

 1 1 0 1 0 0 1 1 0 0 0 1 1 1 0 1

No. 2 Translate each output (v, w, x, y, z) into a Karnaugh map, do the simplification and write down the Boolean equation.
