In this video, the design and working of the Parity Generator and Parity Checker circuit are explained.
The following topics are covered in the video:
0:00 Introduction
1:43 Odd and Even Parity Generator (Working and Design)
5:59 Odd and Even Parity Checker (Working and Design)
For more information, check this video on Parity:
• Error Detecting Code :...
What is Parity?
Parity Bit is a simple form of error detecting code, where the additional bit is added along with the data bits.
There are two types of Parity:
1) Odd Parity
2) Even Parity
Odd Parity:
In odd parity, the parity bit is set in such a way that the total number of 1s in the code, including the parity bit is Odd.
Even Parity:
In Even parity, the parity bit is set in such a way that the total number of 1s in the code, including the parity bit is Even.
For error detection, the parity bit is appended with data bits, and the code is sent to the receiver.
At the receiver, the parity checker circuit checks the parity of the received code and detects the error.
Limitations of Parity Bit:
The Parity bit can detect only odd numbers of errors. If there are even a number of errors in the received code, it will remain undetected.
Moreover, the Parity bit can just detect the error in the code (if the number of errors in the received code is odd) but it can't correct the error.
In this video, the design of the 3-bit Parity Generator and 4-bit parity checker is explained using a truth table.
This video will be helpful to all the students of science and engineering in understanding the design and working of the Parity Generator and Parity Checker circuits.

I spent a lot of time (more than necessary) trying to understand the generator and checker and relation between them with no luck untill I, once again, came across this channel and was saved Thank you sir, I have a test today and you really helped save time❤️

Amazing explanation! Really very well explained these so called appearing to be "complex" portions of parity checker and generator in a very simple way.

13:10 Does that mean that we can make an odd parity checker exactly like an even one, but with XNOR gates instead of XOR?

Can we make parity checker to show 1 for 'no error' and 0 for 'error' using additional not gate? Bro, what if the parity bit itself got changed? Why don't we just say the total 1's of a signal as odd or even without using parity? How can we know the error is on a single bit or in two bits? Is the parity bit always added as MSB or LSB? What can be used to detect errors with more than 1 bit?

@ALLABOUTELECTRONICS 2 жыл бұрын

Yes, you using the NOT gate, you can reverse the logic of the parity checker. If the parity bit itself gets changed and if there is odd numbers of errors in the code then it can be detected using the parity checker circuit. The parity bit can be at the LSB or MSB position. It depends on the detection scheme. But transmitter and receiver should agree to the same scheme. Using the parity checking method we can detect only odd number of errors. We can't detect even number of errors. To detect and correct more than 1 bits error other error detecting and correcting codes are used. For more info, I will encourage you to go through these two videos: 1) Error Detecting Code: kzfaq.info/get/bejne/eN2Zm5qQprqVn30.html 2) Hamming code: kzfaq.info/get/bejne/qpqbnNxlqdncZY0.html

Will the receiver be able to check the parity before receiving the full data bits... Eg- if we are having 5-bit data ... We are transferring data bit by bit and we got an error on the 2nd bit,will it give an error at this time or will it wait until all 5 bits were received....and gives error?

@ALLABOUTELECTRONICS 4 ай бұрын

Receiver will check the parity, once all the 5 bits will get received.
