Step 1 of 1 4.12DP Canonical sum is the sum of minterms corresponding to truth table for which the function produces a high (digit '1') output. Minimal sum is the sum of product terms (min terms) expression for the function. The logic function has fewer product terms. Do not have the other sum of product expression for the same function. Minterm list is also known as on-set of the logic function. The minterms will also have all the n-input literals when the Canonical sum for an n-input logic function is same as minimal sum. In other words, the Minterms in the function does not differ by a single literal with other minterms in the function. Any sum of the expressions with same number of product terms has at least as many literals. Hence the function cannot be simplified using switching algebra axioms and theorems and therefore, the minimal sum is same as canonical sum.
