Before discussing what is a half adder we need to know what is an adder first adder circuit is a combinational digital circuit that is used for adding two numbers.
Binary arithmetic is carried out by combinational logic circuits, the simplest of which is the half adder, shown in fig 411 this circuit consists, in its most. The full-adder is usually a component in a cascade of adders, if you look closely, you'll see the full adder is simply two half adders joined by an or. The half adder is an example of a simple, functional digital circuit built from two logic gates the half adder adds two one-bit binary numbers (ab.Fast ternary addition this half adder works for both unsigned and balanced ternary numbers, since the order of values is the same in both systems.
