Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver . Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data in many cases . </P> <P> Error detection is the detection of errors caused by noise or other impairments during transmission from the transmitter to the receiver . Error correction is the detection of errors and reconstruction of the original, error - free data . </P>
