Logic Gates : XOR and XNOR gates Explained | XOR and XNOR gate as Inverter

In this video, the XOR gate and XNOR gates are explained in detail.
In this video, two input XOR and XNOR gates, the applications of XOR and XNOR gates, and the XOR and XNOR gates with more than 2-inputs are explained. And at the end, how XOR and XNOR gates can be used as an inverter (as NOT gate) is also explained.

XOR gate (Exclusive OR Gate):
The output of the 2-input XOR gate is high when both inputs are different. It can also be implemented using three basic gates. (AND, OR, and NOT gate). In this video, the implementation of the XOR gate using three basic gates is shown.
In general, the output of the n-input XOR gate is high (logic '1'), when an odd number of inputs is high or logic '1'.
Typically, more than a 2-input XOR gate is not readily available and it is implemented using multiple 2-input XOR gates.

XNOR gate:
The output of the XNOR gate is the complement of the XOR gate output. The output of the 2-input XNOR gate is high (logic '1' ) when both inputs are same. (either logic '0' or logic '1'). The XNOR gate can also be implemented using the three basic gates. (AND, OR, and NOT gates). In this video, the implementation of the XNOR gate using three basic gates is shown.
In general, for the n-input XNOR gate, the output is high (logic '1') when the even number of inputs is high (logic '1').
Similar to the XOR gate, more than 2-input XNOR gates are not readily available. And they are implemented using the 2-input XOR and XNOR gates.

Applications of XOR and XNOR gate:
1) Arithmetic Operations (Adder and Subtractor)
2) Code Converter
3) Error Correction and Error Detection

Why I didn't find your channel before 😅 regret!! 😮any how your video lectures helped me lot thank you so much.🤟

[otakulife]

Your videos has helped me tremedeously in preparing for my final exams. Thank you so much for your efforts. It just saved my ass from failing this subject 😺

The output of XNOR gate is always the complement of XOR gate.
It's just that when the number of inputs are even then we can also express the output of XNOR gate in terms of that circle dot symbol using successive XNOR gates.
When the number of inputs are odd then the output is either the complement of 3 input XOR gate or complement of A circle dot B circle dot C.
When the number of inputs are odd then A circle plus B...C= A circle dot B...C
When the number of inputs are even then A circle plus B...C= (A circle dot B...C)'

Since yesterday was waiting for next video and u came 🎉🎉

If there are two 1’s and you add them, it’s gonna be 0? And not 1?

[ameenaharmain]

Eagerly waiting for more videos on logic gates ☺️☺️

Sir, when we take 2 inputs for X-OR gate, in the truth table why for A=1, B=1 we get Y=1? Isn't it Y=0? Sir, please answer me. My Digital Electronics 1 exam is knocking at the door😭

Why are resistors in ohms and megaohms difficult to fabricate, why we use it in kiloohms generally?

You have old videos of more complicated topics in detail . I couldn't join college after 12 . If you can make a playlist of videos from start to end in a sequence or like a course it will be much more helpful . Currently I'm unable to follow . Please do this . I don't follow any curriculum but I want to be a good engineer one day.

10:50 for n input xnor gate when even number of inputs are high then output is also high. But it is not following according to this generalized way. As if we consider 3 input XNOR GATE as follows:
A(XNOR)B(XNOR)C = 0(XNOR)0(XNOR)1= 1 (i.e. odd number of one's)
Similarly 0(XNOR)1(XNOR)0= 1(i.e. odd number of one's)

And for even number of 1s it is giving me 0 as output .
Considering above XNOR expression
0(XNOR)1(XNOR)1=0 ( i.e. even number of 1s)
1(XNOR)0(XNOR)1=0 ( i.e. even number of 1s)

I have two conclusions for n input xnor gate:

1. For even inputs, output is logic high if number of logic high inputs are even.
2. For odd inputs, output is logic high if number of logic high inputs are odd.

Thankyou sir I have understood this concept only cause of you 💫

[richaashtekar]

Plz do Boolean laws too 🙏🙏and demorgan laws

[iramkhan]

I couldn't understand gate structure

[krishk]

What you are trying to say by 3:24 "we can say that it's output is equal to ONE when odd number of inputs are high" It's confusing because the way you identifying odds and evens. which one are odds and which one are even????

[skwayes]

Sir how to simplify XOR Gate to XNOR? How to show A'B'(+) AB.

[MannyaAtwal]

8:23 in XNOR 0 + 0 is 0 the only y =1 is of1+1 =1

[physics]

You are even number of inputs it is 0 or 1
