Error Detection And Correction Ppt
Error is a condition when the output information does not match with the input information. During transmission, digital signals suffer from noise that can introduce errors in the binary bits travelling from one system to other. That means a 0 bit may change to 1 or a 1 bit may change to 0. Error-Detecting codes Whenever a message is transmitted, it may get scrambled by noise or data may get error detection and correction pdf corrupted. To avoid this, we use error-detecting codes which are additional data added to a given digital message to help us detect if an error occurred during transmission of the message. A simple example of error-detecting code is parity check. Error-Correcting codes Along with error-detecting code, we can also pass some data to figure out the original message from the corrupt message that we received. This type of code is called an error-correcting code. Error-correcting codes also deploy the same strategy as error-detecting codes but additionally, such codes also detect the exact location of the corrupt bit. In error-correcting codes, parity check has a simple way to detect errors along with a sophisticated mechanism to determine the corrupt bit location. Once the corrupt bit is located, its value is reverted (from 0 to 1 or 1 to 0) to get the original message. How to Detect and Correct Errors? To detect and correct the errors, additional bits are added to the data bits at the time of transmission. The additional bits are called parity bits. They allow detection or correction of the errors. The data bits along with the parity bits form a code word. Parity Checking of Error Detection It is the simplest technique for detecting and correcting

Error detection techniques add extra parity bits to data to determine when errors have occurred. This activity is a magic trick which most audiences find intriguing. In the trick the http://csunplugged.org/error-detection/ demonstrator is "magically" able to figure which one out of dozens of cards has been turned over, using the same methods that computers use to figure out if an error has occurred in data storage.
