Xor gate circuit diagram. Translate the state diagram to a table make the table look like k maps get the boolean expressions from the k maps draw the circuit from the boolean equations. Xor gate sometimes eor or exor and pronounced as exclusive or is a digital logic gate that gives a true 1 or high output when the number of true inputs is odd.

The xnor gate sometimes enor exnor or nxor and pronounced as exclusive nor is a digital logic gate whose function is the logical complement of the exclusive or gatethe two input version implements logical equality behaving according to the truth table to the right and hence the gate is sometimes called an equivalence gatea high output 1 results if both of the inputs to the gate are. How a logic circuit implemented with aoi logic gates can be re implemented using only nand gates. The leads should be shorted together or the device placed in conductive foam.
From the state diagram you are four steps away from a working circuit. That using a single gate type in this case nand will reduce the number of integrated circuits ic required to implement a. An expression can reference values from other elements in the circuit.
With complete verilog testbench. How a nand gate can be used to replace an and gate an or gate or an inverter gate. The interactive animation allows you to choose any one of the 7 basic gates from the top bar and click switches a and b to test its operation.
An xor gate implements an exclusive or. As a data selector a multiplexer is often depended on to maintain data integrity. D0 d1 d2 and d3a multiplexer is a logic circuit whose function is to select one data line from among many.
Universal gate nand i will demonstrate the basic function of the nand gate. Full adder verilog code with 2 half adders and one or gate. With fig 212 you can check out the operation of the basic logic gates for yourself.
