SimplificationImplicants

• ImplicantA product term is an implicant of a function if the function has the value ‘1’ for all minterms of the product term.

• Prime implicantIf the removal of any literal from an implicant P results in a product term that is not an implicant of the function then P is a prime implicant.

• Essential prime implicantA prime implicant that covers a ‘1’ square which is not covered by no other prime implement rectangles.

• Non-essential prime implicantA prime implicant in which all of its covered ‘1’ squares are covered by one or more other prime implicants.
