### 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.

 Gautami Reddy said: (Sep 30, 2012) 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.

 Pavan Chowdary said: (Sep 10, 2017) 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.
