you must use HA
12 NOR gates are required to implement full adder
by the procedure design a half subtractor design a logic ciruit to add two numbers with five bits each drawthe logic diagram of afull adder using using NAND gates only ?
The full adder takes care of everything, A, B, CarryIN, Sum, and CarryOut. I don't see why you would need a half adder after using a full adder, unless you were trying to process look-ahead carry, but that requires more than just a half adder.
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
hii this is use full persentation
You cannot design a full adder using only OR gates. You also need AND gates. Typically, this can be done with just NAND gates.

i want to get the answer of this ?
A 4bit parallel adder can be implemented by connecting four (4) full adders in parallel that will count from zero to fifteen.
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
A full adder is a logical unit. The full adder must obey truth tables. They are simple, but are not speedy.
Do you mean :- how to get full adders by using half-adders? For this question refer following answer - A full-adder can be obtained by combining two half-adders and one or gate. Details on full-adder and half-adder can be referenced from following link http://www.fullchipdesign.com/fulladder.htm
