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

∙ 10y agoThe half adder adds two binary bits and produces the output(sum and carry).
Full adder adds two significant bits and a previous carry and produces the output(sum and carry).
Combination of two half adder and a OR gate is called a half adder.

Why we use half adder even when full adder is more usefull?
A half adder has less components, and may therefore be cheaper. So, in cases where all you need is a half adder, it may be more convenient to use a half adder. Or it may be more convenient to mass-produce only the full adders, since a full adder can work as a half-adder as well.Also, in introductory electronics textbooks, the half-adder would be introduced first, just because it is simpler.
How to draw the logic circuit for full adder using half adder?
asdfghjkl;' s-sum and c'-carry see for half adder s=a(xor)b and c'=ab for full adder s=a(xor)b(xor)c and c=ab+bc+ac or ab+c(a(xor)b) we can convert two half adder to full adder with help of and or gate. . . ! we got two half adder * for first half adder input is a and b therefore. . .s=a(xor)b and c'=ab * for second half adder input is a(xor)b and c therefore. . .s=a(xor)b(xor)c and c' is (a(xor)b)c note: now connect the c' of first half adder and second half adder to 'or' gate resulting is ab+c(a(xor)b)
What is the difference between half adder and full adder in computer organization and architecture?
A half adder has 2 inputs and 2 outputs, these are usually called something like: Ain, Bin, Sout, Cout.A full adder has 3 inputs and 2 outputs, these are usually called something like: Ain, Bin, Cin, Sout, Cout.A & B are the 2 bits to be added, C is the carry bit, and S is the sum bit. A half adder cannot propagate carry as it has no carry input, a full adder canpropagate carry. A full adder can be built from 2 half adders.
Full subtractor using 2 half subtractor?
The half adder is an example of a simple, functional digital circuit built from two logic gates. A half adder adds two one-bit binary numbers A and B. It has two outputs, S and C (the value theoretically carried on to the next addition); the final sum is 2C + S.
How can draw the circuit diagram if input more than 3 using full or half adder?
You'll need to go to a website that does graphics - it's too complicated to describe in text-only.
Can full adder become half adder?
No. A full adder is two half adders with a carry circuit to combine the two carries together.
Define half adder and full adder?
From wikipedia: A half adder is a logical circuit that performs an addition operation on two binary digits. The half adder produces a sum and a carry value which are both binary digits. A full adder is a logical circuit that performs an addition operation on three binary digits. The full adder produces a sum and carry value, which are both binary digits. It can be combined with other full adders or work on its own.
What is half-adder circuit?
The circuit which adds two single bit binary numbers and produce a sum and carry is a half adder circuit.
Why full adder is better then 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.
What are the major components of a serial full adder circuit?
Two half adders, an OR gate, and a delay.
Presentation on half adder and full adder?
hii this is use full persentation
What are the applications of full adder and half adder?
they are integrated in the calculators
What are applications of half adder and full adder?
they are integrated in the calculators
What is the basic differences between full adder and half adder?
Number of input bits. Half adder: (Cout,Q) := A+B Full adder: (Cout,Q) := A+B+Cin
Why you use half adder after the arrival of 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.
Why we use half adder even when full adder is more usefull?
A half adder has less components, and may therefore be cheaper. So, in cases where all you need is a half adder, it may be more convenient to use a half adder. Or it may be more convenient to mass-produce only the full adders, since a full adder can work as a half-adder as well.Also, in introductory electronics textbooks, the half-adder would be introduced first, just because it is simpler.
How a Full Adder with the help of two Half Adders?
Connect two half Adders with an OR gate to make a Full Adder.
