2. [4 marks] The circuit diagram 1 below is an arithmetic logic unit (ALU). The circuit is designed to perform either logical operations or arithmetic operations using two inputs A and B, and possibly a third input Ci representing a carry-in. The result comes out at the Output, and possibly at a second output Co representing a carry-out. f the following set of inputs are applied to the ALU: S1=1,S0=1,A=1,B=1,Ci=1 (b) Give the result expected at Output and at C0 (if relevant)
