Discussion :: Ex-OR and Ex-NOR Gates - General Questions (Q.No.9)

9. 

Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function.

[A]. Using A as the control, when A = 0, X is the same as B. When A = 1, X is the same as B.
[B]. Using A as the control, when A = 0, X is the same as B. When A = 1, X is the inverse of B.
[C]. Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the same as B.
[D]. Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the inverse of B.

Answer: Option B

Truth table of ex-or gate is.

0 0 0.
0 1 1.
1 0 1.
1 1 0.

Considering 2nd, 4th case answer is B.

According to the truth table of xor gate, a is input b is input and x is output.

Here an input is 0 so b input same as same as x once we check it.
