WebInverse operation of xor. If x = a xor b, given the values of x and a can we find b? In other words, which function can be applied on both sides in the equation to get the value of b? WebThe XOR operator outputs a 1 whenever the inputs do not match, which occurs when one of the two inputs is exclusively true. This is the same as addition mod 2. Here is the truth table: 0 XOR 0 = 0. 0 XOR 1 = 1. 1 XOR 0 = 1. 1 XOR 1 = 0.
