1. Review

a. I want to select between 5 different 2-bit inputs and output it. How many bits do I need to specify which input? Draw an implementation of this using the minimum number of 2:1 Bus MUXes and no other logic.

b. Use one appropriately sized decoder and a small number of AND, OR, and NOT gates to implement the functionality from 1.a.

c. Design a circuit using AND, OR, and NOT gates that takes a 4-bit twos complement number as input and outputs whether the number is positive (p), negative (n), or zero (z). d. How many bits are required to encode the number of ns in a day? e. Convert 0x0FF1CE into binary and decimal.
