It can be calculated via an XOR sum of the bits, yielding 0 for even parity and 1 for odd parity
A parity generator checks the data to be transmitted and outputs a 0(parity bit) if the number of logic 1's in the data is even, and a logic 0 if the number is odd. So a checker takes the transmitted data and the parity bit and will compare the two, and if they are both of the same logic then the you can conclude that the data was recieved succesfully(i.e no bits were lost during transmission). Parity checker/generator use the exact same devices, but with one comparing instead of generating.
Parity bit generator is the error that occures when digital codes are being transferred over channel from one point to other .
The 74180 is a 9-bit Odd/Even Parity Generator and Checker

We check the weather the number of bits at the input are odd or even and assign the parity bit to 1 or 0. And we do the same to check weather the output is the same as the input. Now as the probability of 2 bits going wrong and we may be confident enough just by checking one bit .
assalam o alikum,i am hameed ullah and a student of electronic engineering. my question is that ,,,,,,,,,,, "why we converted a binary number into gray code" and what is the difference in odd parity and even parity
There are two types of parity bits.they are even and odd parity.
A parity error always causes the system to hault. On the screen, you see the error message parity error 1 (parity error on the motherboard) or parity error 2 (parity error on an expansion card)
