Here's a quick note about the topics which will be introduced in this tutorial :Map RollingA pair, quad or an octet can be formed by combining the adjacent ones in rectangular form. A combination can also be obtained by rolling the map (just like a world map is rolled to combine the leftmost and right most edges) along its length or width. This is called map rolling.Overlapping groupsThe groups (pairs/quads/octets) that we form can also overlap each other. It means that a single value can be contained in more than one group. Redundant groupsA group which has all its values also contained in some other groups is called a redundant group. A redundant group must be removed as it just adds extra terms.Here are the kind of the problems you will learn to solve in this tutorial :F = X’Y’Z’ + X’Y’Z + XYZ’ + XY’Z + XYZTo reduce a Boolean expression using Kmap, first make the Kmap for the expression. Now group the 1s in the priority order— Octet quad pair single value. That is, make octets wherever possible than quads than pairs. After that, remove the redundant groups. Then write the reduced terms for the remaining groups and add them all. The result is your reduced expression.
