Q3.
Adders are an essential part of any general-purpose processor. The building block of an n-bit
adder is 1 bit adder which has 3 inputs (X, Y, CIN) and 2 outputs (Sum and COUT). In the class, we
discussed 1-bit binary adder (which can simply be cascaded n times to make an n-bit adder). We
implemented the Sum function, from its truth table, using AND, OR and NOT gates.
Implement the Carry function using the same technique and give its structural description (Logic
diagram).
