Can we make full subtractor from full adder?
Can we make full subtractor from full adder? When configured to subtract, an adder/subtractor circuit adds a single inverter (in the form of an XOR gate) to one input of a full adder module. A ripple borrow subtractor performs the same function as an adder/subtractor in subtract mode, but the two circuits are different as shown below. What is full adder and subtractor explain? In digital circuits, an adder–subtractor is a circuit that is capable of adding or subtracting numbers (in particular, binary). It is also possible to construct a circuit that performs both addition and subtraction at the same...
