1. b) A new function h is made from the f1 and f2 in question 1(a), such that: h = f1 + f2 i) Using a Karnaugh map (not by

using algebra), find a minimum sum of products expressions for h. ii) Demonstrate how the minimum sum of products expression for h could also be found using the Quine-McCluskey algorithm. (Start again with the definitions of h, f, and f2 as given here and in question 1(a).) Show how to find the prime implicants (PIs), and derive the final Boolean minimum sum of products expression, including the use of a prime implicant chart. iii) Which parts of your Karnaugh map in 1(b)(i), if any, represent prime implicants or essential prime implicants? Explain your reasoning (in less than 50 words). You may include a simple diagram to support your discussion.
