Q4. Design the circuit diagram of a 5-bit Adder-Subtractor that can add and subtract two 5-bit Binary Numbers using Block Level Design Method. Whether the unit will be adding or subtracting 2 numbers that will depend on a ' 1 -bit' input 'Sel'. If 'Sel' \( = \) ' 0 ', the unit should perform \( (A+B) \), otherwise it should perform (A-B). Assume 2's complement subtraction. Assume that you already have the Half Adder components (HA), Full Adder components (FA) and necessary gate components. (15 points)
