What are the characteristic of the full adders have?

Full adders are digital circuits that perform the arithmetic addition of three binary bits: two significant bits and a carry-in bit. They have three inputs: A, B, and Carry-in (Cin), and two outputs: Sum and Carry-out (Cout). The Sum output represents the least significant bit of the result, while the Carry-out indicates if there is a carry to the next higher bit. Full adders are essential components in building more complex arithmetic circuits, such as ripple carry adders.
