from Roth's Fundamental of Logic Design, 6E
F(a, b, c, d) = a' + a c' d' + b' c d' + ad
a) Using Shannon's expansion theorem, expand F about the variable d.
b) Use expansion in (a) to realize the function using two 3-variable LUTs and a 2-to-1 mux. Specify the LUT inputs.
c) Give the truth table for each LUT.
