Task 2: 2-bit adder Task 22-bit adder Design and build a circuit that can add together two 2-bit numbers (with a carry-in). Figure 1 illustrates this in two ways: symbolically and with a specific numeric example. Description: (Describe the objective and explain how binary addition works) Description: (Describe and illustrate your design process; Emphasis on connection between longhand addition and how your 2-bit adder is constructed) Circuit Diagram: (delete sample circuit below and this message, and insert your circuit diagram \begin{tabular}{l|l} Figure 1: 2-bit addition with a carry-in. Left side shows this symbolically. Right side provides a specific numeric example. & from task 2) \end{tabular} Figure 2 provides the logic circuit for a full adder (or a 1-bit adder). Use this schematic as the basis for your design. In order to make a 2-bit adder, you will need two full adders that are connected in a special way. In LogicWorks, build your design first as logic gates (to verify that it works), then with chip schematics (for ease of wiring). The formal design process would have included a truth table. How many rows would be needed in that truth table? Discuss the pros and cons of the formal design process and the process used here
