It depends on the protocol that is established between transmitter and receiver. It can be appended at the last (at LSB side) or at the beginning (at MSB side)
Generally the protocol is already been established between the transmitter and receiver, like how many bits will be transmitted. What type of parity is used on in general what type of error detecting and correcting mechanism is used.
Typically for transmitters and receiver the protocol is set for specific parity in advance. Because accordingly you decide the hardware for both transmitter and receiver. So when the receiver receives the data, it already knows which parity is used in transmission. I hope, it will clear your doubt.
In that case also, the parity checker circuit will generate the error. In short, if the parity of transmitted and the received code doesn't match then it will generate the error. (Irrespective of whether the error is in data bit or in the parity bit)
Sir,I have a doubt.We are adding parity bits for error detection ie since data is getting corrupted we are adding parity bits.But doesn't a condition occurs like parity bits can get corrupted and the error detection can go wrong
Yes, it is quite possible that the parity bit itself gets corrupted during the transmission. But as far as there is an odd number of errors in the code, it is still possible to detect the error. Let's say, we are sending the data for odd parity. The parity bit will be set in such a way that, the total number of 1s in the code is odd. Now, suppose, the parity bit gets corrupted then the total number of 1s in the received code will become even. And since it is even, the parity checker circuit will be able to detect the error. I hope, it will clear your doubt. If you still have any doubt then let me know here.
@@ALLABOUTELECTRONICS Sir,let me explain my doubt with an example.Consider I am sending 3 bit data 011 and then we are using odd parity for error detection.So the data along with parity that will be transmitted is 0111.Now assuming that the parity bit is corrupted and the data received at receiver is 0110.The receiver will find the number of one's to be even and there is an error.Receiver will expect the number of bits in the data bits had to be odd,so the error is in data.Now assuming the second case,where the second bit of data was corrupted while transmission and then data received at the receiver along with the parity bit be 0011.(Here data is corrupted).Here also receiver finds that the number of one's are even and there is error.But how to differentiate whether data is corrupted or parity bit is corrupted.
See, this code( parity) is error detecting code. Meaning that, it can just tell you that, there is some error in the received code. It just can't correct the error. Or it can't tell you the location of the error. For that, error correcting codes are used. I think I have mentioned that at the end of the video. And on the Channel I have also covered couple of videos on Hamming distance and Hamming code. ( It is error correcting code). Please go through those videos. Your doubts will get clear. I have explained it in detail. Please go through the digital electronics playlist on the channel. You will get those videos. In case, if you are not able to find it, let me know here.
@@ALLABOUTELECTRONICS hi, what if 2 bits are corrupted for example 1 goes into 0 and other where zero goes into one it will not change the number of 1's, so how will it detect the error?
Then also it will be able to detect the error. Because at the receiver side, the parity checker circuit will check the parity of entire code ( including parity bit ). So if there is an error in parity bit then also it will detected. I hope it will clear your doubt.
If there are even number of errors in the received code then parity checker won't detect it. You need to use other coding schemes to detect such errors. On such error correcting scheme (Hamming Code ) is discussed on the channel. You can watch that video for more information. Here is the link: th-cam.com/video/t4kiy4Dsx5Y/w-d-xo.html
what happened if two bits are corrupted at a time? for example : data iam sending is 110011001 including parity bit (odd parity), but at the receiver side i got 110000001, how we can detect this error ?
Your assumption is correct. If two bits are corrupted at a time in a parity-based system, the parity bit can't correct the error. Parity can only handle single-bit errors within its group of bits. More advanced error correction techniques like "Vertical Parity", "LRC", or "CRC" (checksums) are used in modern systems to ensure data remains correct. The sophistication level depends on factors like signal strength, data loss, and the importance of accurate data. If you're interested, read up more on checksums :)
Even if the parity bit gets flipped, then also the error can be detected. As far as the number of error in the code is odd, it can be detected using the parity method. When there is an error in the parity bit then overall parity of the received code will change. For example, if you are using the odd parity then parity bit at the transmitter should be set such that, the overall parity of the code remains odd. Now, if there is an error in the parity bit itself then that would change the parity of the received code. And that would be detected at the receiver end by the parity checker circuit.
@@ALLABOUTELECTRONICS Thanks dude Its been two years since this video was uploaded You are still replying with half million subscribers. Means a lot to me. Also you explained the concept very well that I figured that out.

The thing is when we use Odd parity then parity bit should be set such that the overall parity of the code (including parity bit) should remain odd. And the same is applicable for even parity.

Thank you so much sir. 😀😄
Thanks for such a useful VEDIO 🙏🙏
Thanks sir.It's clear and easy to understand.
In real world practice, how accurate is it to use a parity bit as an error detector?
Not accurate
Well defined 😊
It was helpful .. thank you
2:43 Should we add the parity bit at right side or left side of 8 bit number
It depends on the protocol that is established between transmitter and receiver. It can be appended at the last (at LSB side) or at the beginning (at MSB side)
How does the parity checking network decides what parity we have opted(even or odd)?
hard code then
Fantastic sir ....
5:00 Sir how the Receiver comes to that whatever data has been transmitted contains odd or even number of bits??
Generally the protocol is already been established between the transmitter and receiver, like how many bits will be transmitted. What type of parity is used on in general what type of error detecting and correcting mechanism is used.
@ALLABOUTELECTRONICS thank you
Thank you so much Sir 🙏🙏💐💐
Thanku sooo much sir 😍
Good explanation but the parity bit should be added to MSB (most sognificant bit) isn't it.
No, not necessarily. It can be either MSB or LSB. That depends on the protocol established between transmitter and receiver.
Oh yes, I got it@@ALLABOUTELECTRONICS
Well done man
Thanks alot sir💫
But what if we do not know which parity is used?(Even or Odd) How will we know if the recieved pattern is correct?
Typically for transmitters and receiver the protocol is set for specific parity in advance. Because accordingly you decide the hardware for both transmitter and receiver. So when the receiver receives the data, it already knows which parity is used in transmission. I hope, it will clear your doubt.
@@ALLABOUTELECTRONICS Thank you. It is clear ♥️

What if the parity bit is flipped? There are no guarantees the parity bit will not flip. What then?

Thank you so much sir
What if parity bit only changes from 0 to 1 while transmission
Then also it will be able to detect the error. Because at the receiver side, the parity checker circuit will check the parity of entire code ( including parity bit ).
So if there is an error in parity bit then also it will detected.
I hope it will clear your doubt.

Even if the parity bit gets flipped, then also the error can be detected. As far as the number of error in the code is odd, it can be detected using the parity method.
When there is an error in the parity bit then overall parity of the received code will change. For example, if you are using the odd parity then parity bit at the transmitter should be set such that, the overall parity of the code remains odd.

If there is an error in the parity bit, then also it will get detected. As far as the number of errors in the received codes are odd, the error will be detected. But if there is an even number of error in the received code, then it won't be detected.
I don't know but u are mixing odd parity and even parity I watch three times but same confusion
