Select the K-map according to the number of variables.Identify minterms or maxterms as given in the problem.For SOP put 1’s in blocks of K-map respective to the minterms (0’s elsewhere).For POS put 0’s in blocks of K-map respective to the max terms (1’s elsewhere).1. K-map of 3 variables
From redgroup we get product term— Fromgreengroup we get product term— Summing these product terms we get- Final expression (A’C+AB)
2. K-map for 4 variables
From redgroup we get product term— From greengroup we get product term— Summing these product terms we get- Final expression (QS+Q’S’).
1. K-map of 3 variables
