The logic diagram includes an and gate and two half subtractor circuits which are further an or xor and and not gate combination.
The code for the full adder is also shown for completeness. Design and implement a 4 bit full adder. For the coding part as said earlier we need to take a look at the logic diagram for the structural style of modeling. 4bit full adder aim.
