Digital Logic Circuits and Boolean Minimization Techniques
Binary Adders and Subtractors
A Half Adder is a combinational logic circuit that adds two single-bit binary numbers. It produces two outputs: Sum (S) and Carry (C). It is called a ‘half’ adder because it cannot handle a carry from previous additions.
