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.

In order to generate the parity check matrix you must first have the generator matrix and the codeword to check and see if it is correct. 1. Place your generator in row reduction form 2. Get the basis vectors 3. Put the vectors together to get the parity check matrix 4. Check it b multiplying the codewords by the parity = 0 For an example: 2*4 Generator Matrix [1 0 1 1 0 1 1 0] Rank = 2...therefore the number of columns is 2...Rank + X = # of columns of the Generator matrix v1+v3+v4 = 0 v2+v3 = 0 v1 = -r1-r2 v2 = -r1 v3 = r1 v4 = r2 Parity = [-1 -1 -1 0 1 0 0 1]

parity error

In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.

It can be calculated via an XOR sum of the bits, yielding 0 for even parity and 1 for odd parity

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 .
