__________ is a disjunctive normal form.(a) product-of-sums(b) product-of-subtractions(c) sum-of-products(d) sum-of-subtractionsI have been asked this question by my school teacher while I was bunking the class.The query is from Boolean Functions topic in portion Boolean Algebra and Modeling Computations of Discrete Mathematics

Answer»

The CORRECT answer is (c) sum-of-products

The BEST I can EXPLAIN: The sum of MINTERMS that represents the function is called the sum-of-products expansion or the disjunctive normal form. A Boolean sum of minterms has the value 1 when exactly one of the minterms in the sum has the value 1. It has the value 0 for all other combinations of values of the variables.
