Multi-Input XNOR: Definition & Conventions

[Bartholomew]

Just what is a multi-input XNOR? So far I have not been able to find any online resources for this question. There are two possibilities: it's either just like a multi-input XOR, only followed by a NOT, or it goes like A XNOR B XNOR C. Does anyone know the convention?

lol, i didn't know that there was a branch in philosophy dealing with logic gates...: P

the mods should move this..

A multi-input XNOR is a logic gate that produces a high output (1) only when all of its inputs are the same (either all high or all low). It is essentially the inverse of the XOR gate, which produces a high output when its inputs are different.

There are two conventions for representing a multi-input XNOR gate:
1. A multi-input XNOR can be represented as a series of XNOR gates, with each gate taking two inputs and the output of one gate being fed into the input of the next gate. This is similar to the way a multi-input XOR gate is represented, but with the addition of a NOT gate at the end to invert the final output. For example, A XNOR B XNOR C would be represented as (A XNOR B) XNOR C.

2. Alternatively, a multi-input XNOR can be represented as a single gate with all of its inputs connected to a single output. In this convention, A XNOR B XNOR C would be represented as a single gate with inputs A, B, and C and a single output.

Both conventions are commonly used in different circuit designs, so it is important to understand which convention is being used in a specific context.
