![]() ![]() Even one bit of change in data may affect the whole system’s performance. The data errors will cause loss of important / secured data. In this case, the input data is not same as the received output data. ![]() It may be affected by external noise or some other physical imperfections. The data can be corrupted during transmission (from source to receiver). Almost in all electronic devices, we find errors and we use error detection and correction techniques to get the exact or approximate output. The change in position of single bit also leads to catastrophic (major) error in data output. This sequence of bits is called as “Data stream”. In digital systems, the analog signals will change into digital sequence (in the form of bits). It then appends the remainder called CRC bits to the end of data segment. Here, the sender performs binary division of the data segment by the divisor. The divisor is generated using polynomials. Cyclic Redundancy Check (CRC) involves binary division of the data bits being sent by a predetermined divisor agreed upon by the communicating system. ![]()
