An Xor gate has 3 inputs w x y and its output is z. If you invert one of the inputs, what will the output be? Show this in terms of a boolean expression and no matter which input you invert, the output will be the same.
What is this type of gate called?
Also, what happens if you invert all three inputs?
w XOR x XOR y = z
w'x'y + w'xy' + w'xy + wx'y' + wx'y + wxy' = z => expanding xor using and or and not gates
The Attempt at a Solution
If you invert one of the inputs then still you will have 2 combinations of w,x,y for which z=0 and the rest of the input combinations =1. But I do not see how to find the new output function z when you invert one of the input and then find a special gate for that expression. Just out of guessing, I think the gate is XNOR because it is a special gate often used in boolean expressions. Also, if all the inputs are inverted then it would still be an xor right?
