Karnaugh Map Simplification Rules | Grouping Cells

Karnaugh Map is the method used to minimize and simplify the Boolean functions. It works on the basis of complement laws: X +X’ = 1 and X.X’ =0. Thereby, to cancel a variable in K-Map, we need pairs of variables and their complements which is done by grouping. K-Map uses some rules for grouping of adjacent cells. In this video, we will check out simple explanation for these rules, one by one. Karnaugh Map Introduction:    • Karnaugh Map | Introduction (Basic)   Boolean Simplification using Boolean laws:    • Simplification Of Boolean Expressions | Us...   Rule 1: For minterms, groups may include only 1s; zeros are never allowed. Similarly, for maxterms, groups may include only 0s and 1s are never allowed. Rule 2: Groups may be horizontal or vertical; Diagonal groups not allowed. Rule 3: Groups must contain 1, 2, 4, 8, etc terms (that is the total terms of the group must be in powers of 2). Groups made up of 3, 5 terms are not allowed. Rule 4: All the ones in K-Map must be covered by at least one group. Rule 5: Groups should always be fewer in number and larger in size. Rule 6: Overlapping groups are permitted. Rule 7: Groups may wrap around the table (K-Map). Please subscribe our channel CSPictorial for more computer tutorials: #cspictorial
