WebFig 2 – Ripple carry adder Stages. In 4 bit adder, the time delay for a valid output is the sum of time delay of 4 full adders, if there is an ‘n’ bit adder, than the time delay will be the sum of time delay of ‘n’ full adders. It means, higher the bit size of the numbers, the late the answer we will get.So it is not an efficient design for complex and fast working systems. WebLet’s see an example of adding two single bits. The 2-bit half adder truth table is as below: Half Adder Truth Table. 0+0 = 0 0+1 = 1 1+0 = 1 1+1 = 10. ... A FA circuit is used as an element in many large circuits such as Ripple Carry Adder.
