View 4 Bit Ripple Carry Adder Truth Table UK. It consists of 8 full adders which are connected in cascaded form. Here's a truth table that shows all the possible inputs and outputs for a half adder

Principles of computer architecture - arithmetic from softmath.com

Redundant hardware speeds carry calculation compute two. Overflow is 1 when output is more than 4 bits. Circuit adds or subtracts 2s complement:

It is not the most efficient adder because the higher stages in the cascade have to wait for the previous stage to compute carry out bit.

A simple 4 bit ripple carry adder is shown below. So in a sense, it is already computed. Circuit adds or subtracts 2s complement: The truth table of full adder is shown below.

Finally a half adder can be made using a xor gate and an and gate.
