Draw a 3-bit full adder using three 1-bit full adders to add two 3-bit numbers A and B. You may use 2 input/1 output AND, OR, XOR and 1 input/1 output NOT gates. See Module 3 for an example of a 1-bit full adder. Hint: Your circuit will have the following inputs and outputs: Three A inputs labelled A0, A1, A2 Three B inputs labelled B0, B1, B2 Initial Carry-In input labelled Carry-In0 Final Carry-Out output labelled Carry-Out2 Three SUM outputs labelled Sum0, Sum1, Sum2 Note: There will be 2 Carry-In inputs and 2 Carry-Out outputs inside the circuit that are used to connect the full adders but that are not considered as outputs for the circuit. These 2 internal wires do not need to be labelled.

Hint: Your circuit will have the following inputs and outputs:

Three A inputs labelled A0, A1, A2

Three B inputs labelled B0, B1, B2

Initial Carry-In input labelled Carry-In0

Final Carry-Out output labelled Carry-Out2

Three SUM outputs labelled Sum0, Sum1, Sum2

Note: There will be 2 Carry-In inputs and 2 Carry-Out outputs inside the circuit that are used to connect the full adders but that are not considered as outputs for the circuit. These 2 internal wires do not need to be labelled.
