XNOR gate is called coincidence gate
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.
AND
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.
NOT gate
because the gate was gold so thats why they called it the golden gate bridge
Coincidence.
coincidence?
that was the Ishtar gate.
The XOR (exclusive OR) gate is often referred to as an "anticoincidence gate" because it outputs a true (1) signal only when the inputs differ from each other. In other words, it produces a high output only when exactly one of its inputs is true, which is the opposite of coincidence (where both inputs would be true or both false). This unique property makes it useful in applications where differentiation between two states is crucial.
Coincidence.
Nothing Its called coincidence
A lytch gate.
