1) Expand the following function about the variable b.
F= ab’cde’+ bc’d’e + a’cd’e + ac’de’
2) Use a 4-to-1 multiplexer and a minimum number of external gates to realize the function
F(w, x, y, z)= Σm(2,6,8,9,11,15) + Σd(5, 10,13).
The inputs are only available uncomplemented (Hint: K-map, and use w, z on selection lines).
