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. Learn the definition, logic symbol, truth table, and Boolean expression of XOR gate , a derived logic gate that determines the dissimilarity between two signals. See how XOR gate can be used as an inverter, a buffer, and a switching circuit. After understanding the gates and their operation we will use those gates to design a combinational circuit to replicate the XOR gate . We will look into the steps required to design the logical circuit using the three types of gates by using the logical expression of the XOR gate . We will further verify the circuit using the truth table. 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 ...
