Electrical Xnor Gate Circuit Diagram. The truth table of ex nor gate is show in below figure. Hence the nor gate is the inverse of an or gate and its circuit is produced by connecting an or gate to a not gate just like an or gate a nor gate may have any number of input probes but only one output probe.
An xnor gate is also called exclusive nor gate or exnor gate in a two input xnor gate the output is high logic 1 or true when two inputs are same. The logic circuit diagram for this exclusive gate is designed in the combination of and and or gate at the output. A nor gate not or gate is a logic gate that produces a high output 1 only if all its inputs are false and low output 0 otherwise.
According to the truth table given above sum of product expression and schematic for 3 input xnor gate is given below.
The above truth table s binary operation is known as exclusive or operation. Truth tables list the output of a particular digital logic circuit for all the possible combinations of its inputs. An xor gate is also called exclusive or gate or exor in a two input xor gate the output is high or true when two inputs are different.
