This correction is known as the Time Error Correction (TEC). Memory modules may include additional devices for parity checking or error correction. This problem has applications in error detection and correction. The Hipparcos data was examined again with more advanced error correction and statistical techniques. The ordinary user may not be aware of many applications using error correction. CRCs can be used for error correction (see bitfilters). IQR codes add error correction level S, which allows for 50% error correction. There are three major types of error correction. The 14.8% increase is due to the discarding of error correction data. He and Laurer added two more digits to the ten for error correction and detection. Question marks indicate uncertainty about that particular sign being the result of a correction. A number of techniques for surgical correction exist. There is little error correction in TPR. I have to make a slight correction. The word "coded" comes from the use of forward error correction (FEC).
