Discussion Overview

The discussion revolves around the construction and understanding of the XNOR gate, particularly in relation to its derivation from XOR and NOT gates. Participants explore the truth tables associated with these gates and the logic behind their configurations.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested, Homework-related

Main Points Raised

  • One participant questions the clarity of the original question regarding the XNOR gate's definition and its relationship to XOR and NOT gates.
  • Another participant asks for the truth tables of the gates involved, indicating a need for clarity in the logic operations.
  • A participant provides a truth table for the XNOR gate, suggesting that it aligns with the expected output for given inputs.
  • One participant expresses skepticism about the classification, proposing the term "NXOR" and presenting a mathematical representation of the XOR operation.
  • A participant mentions the use of inverters, ANDs, and ORs in the context of logic design, indicating their current study in the field and potential for further questions.

Areas of Agreement / Disagreement

There appears to be some agreement on the identification of the XNOR gate, but skepticism exists regarding the terminology and definitions used. The discussion remains somewhat unresolved, with differing views on the classification and understanding of the gates.

Contextual Notes

Participants have not fully clarified the assumptions behind their statements, and there are unresolved questions regarding the definitions of the gates and their truth tables.

Who May Find This Useful

This discussion may be useful for students and individuals interested in digital logic design, particularly those studying the relationships between basic logic 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?
 
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<br /> \[<br /> \overline {XOR} <br /> \]}[/itex]


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
