LRC stands for Longitudinal Redundancy Check, which is an error detection technique used in data communication. It works by adding a parity bit to each column of the data, and then calculating a parity bit for the set of parity bits. The resulting LRC is transmitted along with the data and is checked at the receiving end to detect any errors.
Here is an example of how LRC is used:
At the receiving end, the data is divided into columns and the parity bits are calculated. The parity bit for the set of parity bits is then calculated and compared to the received LRC. If they match, the data is considered to be error-free. If they don’t match, an error is detected.
