Make Two bit adder circuits

2.1 Make 2 full adder circuits using logic gates named Circuit 1 & Circuit 2. After you complete making 2 full adders , connect them with the carry Output form one circuit 1 going into the carry Input of the Circuit 2 to form a 2-bit adder. Label the inputs A₁A₀, B₁B₀ and the outputs C₁S₁S₀. Test the circuit 16 times adding different numbers (from 0+0, 0+1 to 3+3) and prepare a truth table for this 2 bit adder listing data inputs A₁A₀ and B₁B₀ on the left and the data outputs the outputs C₁S₁S₀ on the right (please arrange the columns in the truth table in the order specified here with the outgoing carry on the left).

2.2 Rework the truth table form Question 2.1 showing the decimal equivalents of the two bit inputs and, this time, the decimal equivalent of the three bit output. For example, considering the inputs A₁A₀ and B₁B₀, and all three outputs C₂S₁S₀, one of the cases in binary is 01₂ +11₂ = 100₂, then in decimal it would be 1+3=4. (Redo the entire truth table using decimal values.)
