For the function f(w,x,y,z) = E (m4, m7, m8, m9, m10, m12, mi13, m15), complete the parts of this question below. (a) Draw and fill in a correct, properly-labelled Karnaugh map for f(w,x,y,z). (b)...

Extracted text: For the function f(w,x,y,z) = E (m4, m7, m8, m9, m10, m12, mi13, m15), complete the parts of this question below. (a) Draw and fill in a correct, properly-labelled Karnaugh map for f(w,x,y,z). (b) List ALL sum-of-prod. prime implicants, and identify which ones are essential. (c) Write the complete least-cost sum-of-products expression for f(w,x,y,z). (d) Now consider m2, m5, and m11 as don't-care cases for f(w,x,y,z) in part (a). Provide the least-cost sum-of-products expression using this information.
