First, we need to prepare; a good hero is always prepared. We should be ready for anything that happens, so let's build a function block. A function block will allow us to select a function for two inputs: A and B using three selector inputs SO, S1 & S2 S1 SO Function Description (Output) Always 0 0 0 | 1 O Logical OR A+B S2 S1 SO Logical NAND ( AB) 0 1 1 Function Block AOB Logical XOR Logical XNOR O ( AB) 0 1 Logical AND AB Logical NOR (A + B) 1 Always 1 1 Problem 1. Using a single 8 to 1 MUX and logic gates, implement the function block
