It is basically an AND operation of OR operated variables such as Y = (A+B).(B+C).(A+B+C) Minterm: - Product term containing all the k variables of the functions is either complimented or uncomplimented form is Minterm. Canonical form of sum of product: - It is defined as the logical sum of all the minterms derived from the rows of a truth table for which value of the function is 1. It is called a minterm canonical form. The canonical sum of product expression can be given in a compact form by lis...
