Chap#10 (Forouzan) Error Detection and Correction 1 Attachment(s) Chapter number 10 Behrouz A Forouzan Error Detection and Correction Contents : Single-Bit Error: In a single-bit error, only one bit in the data unit has changed. Burst Error: A burst error means that 2 or more bits in the data unit have changed. Four Methods of Error Detections:
Error detection uses the concept of redundancy, which means adding extra bits for detecting errors at the destination. In parity check, a parity bit is added to every data unit so that the total number of 1s is even (or odd for odd-parity). Simple parity check can detect all single-bit errors. It can detect burst errors only if the total number of errors in each data unit is odd. |
