XOR, or "exclusive OR," outputs true only when the inputs differ, and achieving this function typically requires a complex combination of logic gates. In traditional circuits, more than a dozen ...

XOR Function XOR (exclusive or) is a vital logical operation that’s used in various capacities in a lot, if not all, cryptographic algorithms. Figure 1 shows how this function works.

As designers, we're used to representing digital functions using Boolean expressions in conventional sum-of-products or product-of-sums forms, which we predominantly implement using AND, OR, NAND, NOR ...

When the “Log. 1” and/or “Log. 0” level signals are applied to the control inputs X1, X2 or F (Mode), the signals at the outputs Y1 AND, Y2 OR and Y3 XOR change in accordance with Table 1. Table 1 ...
