Plotting (Mapping) Functions in Canonical Form on a K-map
Let f be a switching function of n variables where n ? 6.
Assume that the cells of the K-map are numbered from 0 to 2n where the numbers correspond to the rows of the truth table of f.
If mi is a minterm of f, then place a 1 in cell i of the K-map.
Example -- f(A,B,C) = ?m(0,3,5)
If Mi is a maxterm of f, then place a 0 in cell i.
Example -- f(A,B,C) = ?M(1,2,4,6,7)
If di is a don’t care of f, then place a d in cell i.
