Hello students in this question we have to show that how a full adder can be converted to a full subtractor with the addition of one inverted circuit.
00:08
Now first of all we see the diagram for full adder circuit full adder circuit so for full added circuit let us see the diagram.
00:25
So suppose over here this is a and this is over here b so we have over in north and then this is the output over here.
00:45
Then again a and over this is the output and again then a and b goes into an and gate and gate and we have a c input which goes over here the c input and we have the c input and we have the a so the c and a input goes to an and gate and gate and the output of these two and gates goes to a or gate and this is the c out.
01:38
Whereas we have a over here and we have c and we have again over here.
01:49
Then we again have c.
01:52
This goes through a nor gate and this is over s this is the full adder circuit now if we see full subtracted circuit subtracted over here so we have a b and c a and b goes to a norgate goes to a norgate over here then we have a and this is overhead c so we have a again and then we have b so a is passes through a not gate and then a knot and b passes through an and gate this is an and gate over here now the c over here this c and the output of a b through the nor passes through another nort gate this is over here d this the output of the a nb nort gate passes through a nort gate and then c passes through and gate now the output of these two passes through a nor gate and we have the output b out so this is the full subtracted circuit now if we may full adder circuit with full adders configured for subractor circuit, we see this is full adder configured for subtractor.

So we see, so we have a over here which passes through a node gate, then we have b, then we have bn.
04:18
So these two passes through a nor gate over here.
04:26
These two passes through a nor gate.
04:28
This is a dash nor b over there.
04:34
Then we have again a...
