Truth table for 3 input xnor gate?

Best Answer

A, B and C are inputs, Q is output.

A B C Q

0 0 0 1

0 0 1 0

0 1 0 0

0 1 1 1

1 0 0 0

1 0 1 1

1 1 0 1

1 1 1 0

*update*

Although the Logism software shows the 3 input XNOR gate output 1 when all 3 are 1, perhaps there is a mistake, and 3 input of 1,1,1 in an XNOR gate

outputs 0. There is a good reason why. In an XOR gate, an even amount of 1 or 0 input will output a 0, and an odd input of 1 (ie: 1, 1, 1) will output a 1. The truth table

for an XOR gate with 1, 1, 1 input is an output of 1. An XNOR gate will output the opposite of an XOR gate, thus XNOR input of

1, 1, 1 should output 0.

Why XOR and XNOR gate is not known as universal gates?

All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).


What is an XNOR gate?

An XNOR gate is a logic gate performing a Boolean logic XNOR operation, also known as an equivalence gate.


Why X-NOR gate is called a coincidence checker?

If you take a look at the truth table of XNOR (for example, check the Wikipedia article on XNOR), you'll see that the output is true (or 1) exactly when both inputs are the same.


Why XOR gate and XNOR gate are not universial gate?

xor and xnor gates are derived from not gate

What gate is called coincidence checker?

XNOR gate is a two input gate.And if two inputs are the same they are Known as the Coincidence gate.Electronics can be very interesting if you understand the fundamentals of it.


Which logic gate is a basic comparator?

Either XOR or XNOR can be used, but the output will be inverted on the XNOR.

Making of X-nor gate with the help of ic?

the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
