implement it. enough said.
12 NOR gates are required to implement full adder
Maybe you don't wanna understand or basically don't have to dear it's your decision
9,to implement a half adder 5 nand gates and for a full adder,another xor gate is required consisting of 4 nand gates. thus a total of 9 nand gates are required for a full adder.
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.
more logic gates are used instead
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 ?
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
