# XNOR gate

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?

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

$\mbox{\Huge $\overline {XOR}$}$

Best

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
