5. Implement the Boolean function F(A,B,C,D)- 2(1, 2, 5, 7, 8, 10, 12,14, 15) based on using a 8-to-1 multiplexer. (10%) 6. What is the difference between a decoder and a demultiplexer? Give your explanations with circuits. (10%) Assume there are two sets of data, A and B each with 2-bit width, and they may be delivered to either of the two persons, X and Y located at remote place. Due to the connection between the two terminals is constrained as less lines as possible. How do you solve this problem? (10%) 7. 8.
