**Digital : Image – XOR as Inverter **

Where

A and B are two Inputs to the XOR Gate and Y is the Output

According to the diagram, One input is tied with Logic ‘1’

=> Y = A.(1)’+ A’.1

=> Y = 0 + A’

=> Y = A’

**Summary : If we tie one input of an XOR Gate with Logic value ‘1’ then XOR works as an Inverter**

The X-OR gate can also be used as a pass Gate or a buffer that means it can be used to transmit the same input signal to the output.

Let look into the given figure

**Digital : Image – XOR as Pass Gate **

One of the inputs of XOR gate is tied with Logic Value 0.

From the output equation of the XOR Gate –

Y = AB’ + A’B

Where

A and B are two Inputs to the XOR Gate and Y is the Output

According to the diagram, One input is tied with Logic ‘0’

=> Y = A.(0)’+ A’.0

=> Y = A + 0

=> Y = A

**Summary : If we tie one input of an XOR Gate with Logic value ‘0’ then XOR works as a buffer that mean whatever we give at the input, same would appear at the output **
