In summary, the conversation discusses the creation of an XNOR gate using cascaded XOR and NOT gates. The output of the NOT gate is equivalent to that of an XNOR gate. The conversation also mentions confusion about the terminology and truth tables for XNOR gates. It is suggested to use inverters, ANDs, and ORs in place of XOR gates.

This question really doesn't make much sense to me.
We will be creating the XNOR gate by cascading the output of the XOR gate, into the input of a NOT gate. The output from the NOT gate would then be the same as that from an (fill in the blank) gate.
Does XNOR go in the blank? Or did I misunderstand the question?

What do the truth tables look like?
 
  • #3
XNOR sounds right to me, the truth table should be

A B Y
0 0 1
0 1 0
1 0 0
1 1 1

Seems a little odd to me: maybe it's a NXOR or

[itex]
\mbox{\Huge
\[
\overline {XOR}
\]}
[/itex]

X (XOR) Y = X'Y+XY'

they prolly what you to replace the XOR with inverters, ANDs, ORs

I'm taking Logic design right now so i'll prolly be posting some more questions up here
 

Related to XNOR Gate: The Combination of XOR and NOT Gates

What is an XNOR gate?

An XNOR gate is a type of logic gate in electronics that performs the logical operation of equality. It outputs a true value only when both of its inputs are either true or both false.

What is the symbol for an XNOR gate?

The symbol for an XNOR gate is a combination of the symbols for an AND gate and a NOT gate. It consists of two inputs, a single output, and a curved line connecting the two inputs to the output.

What is the truth table for an XNOR gate?

The truth table for an XNOR gate is as follows:

Input A Input B Output
false false true
false true false
true false false
true true true

What is the difference between an XNOR gate and an XOR gate?

An XNOR gate outputs a true value when both of its inputs are either true or both false, while an XOR gate outputs a true value only when one of its inputs is true and the other is false. In other words, an XNOR gate is the inverse of an XOR gate.

How is an XNOR gate used in digital circuits?

An XNOR gate is commonly used in digital circuits to compare two binary values and determine if they are equal. It can also be used as part of a larger logic circuit to perform more complex logical operations.
