After checking all the parity bits, a binary word is formed taking the result bits for P1 as LSB. WebTherefore, to detect and correct the errors, additional bit(s) are appended to the data bits at the time of transmission. Each parity bit checks the corresponding bit locations and assign the bit value as 1 or 0, so as to make the number of 1s as even for even parity and odd for odd parity. Encode a binary word 11001 into the even parity hamming code. Given, number of data bits, n =5. Let us try P=4. The equation is satisfied and so 4 redundant bits are selected.
