Now, given that the above circuit was packaged into one module (sub-circuit) as shown below, your task in this part is to design a 3-bit Arithmetic unit out of the 1-bit sub-circuit shown below. Indicate all bits numbered 2-0 with 2 identified as MSB and let the unit generate one more output that indicate e overflow. (You must label all connections) 2) Mode Cout1-Bit AU Cin
