Another way to describe the process of obtaining the simplified logical expression for a group is to eliminate the variable(s) for which the corresponding bitsMap rolling. Overlapping and redundant groups. Examples of reducing expressions via K-Map techniques. Introduction to Combinational Circuits : Part 1 Karnaugh Maps : Part 2 - Map Rolling, Overlapping groups, Redundant groups - and some examples and problems · Number System · Overlapping groups · Redundant groups. A redundant group is a group in which all the 1 s in a group are overlapped by other groups. Redundent group should be eliminated before
