4. Parts (a), (b), and (c) refer to the following Boolean expression: F=A(B+CD)+ACD a. (10 points) Create a truth table for the expression. b. (10 points) Simplify the expression using a Karnaugh map. c. (10 points) Draw the two-level logic diagram for the simplified expression using only NAND gates and inverters. Assume that the complements of the inputs are not available..
