Design a circuit to add two 2-bit binary numbers and display the results of the addition as a 3- bit binary number. To do this, you will use the four switches on your Breadboard Companion as your two 2-bit number inputs. Your four LEDs will be used to represent the 3-bit output of your circuit. Complete a truth table for the expected output values on the lab data sheet attached. Use Karnaugh maps or other techniques to simplify the Boolean functions for the outputs, and design implementations of the circuit using 1. only AND, OR, and NOT gates. 2. only NAND (NOT is okay only for producing complemented inputs (a, b, etc.))
