Learn what an exclusive OR gate ( XOR ) is, how it works, and why it is useful in digital logic circuits. Find out the symbol, truth table, Boolean expression, and examples of XOR gates and their applications in arithmetic, error detection, and cryptography. XOR gates are used in circuits that perform arithmetic operations and calculations, especially in half-adders and adders. The ability of the XOR gate to compare two logic levels and give an output dependent upon the input condition is very useful in many computational circuits. The XOR or Exclusive OR Gate is a special type of logic gate used in digital electronics to perform the exclusive OR operation. This gate takes two inputs and produces an output depending on the combination of the two inputs applied. 1 What is Logic XOR or Exclusive-OR Gate ? 1.1 XOR Gate Logic Symbol, Boolean Expression & Truth Table 1.1.1 XOR Gate Symbol 1.1.2 Boolean Expression 1.1.3 Truth Table 2 XNOR Gate Logic flow Schematic Diagram 3 Construction and Working Mechanism of XNOR Gate 3.1 XNOR Gate Using BJT and Diodes 3.2 XNOR Gate Using MOSFET and Diodes 3.3 XNOR Gate From other Logic Gates : (Combinational Logic) 3.3.1 Sum of Product 3.3.2 Product of Sum 3.4 XNOR Gate From Universal Gates 3.4.1 XNOR Gate From NAND ...
