WebMar 3, 2013 · Consider the 4-bit generator, G = 1001, and suppose that the data portion of a bit stream to be transmitted prior to Cyclic Redundancy Check (CRC) calculation is 11001001. Show the actual bit stream transmitted. Suppose the leftmost bit in the transmitted bit stream is inverted due to noise on the transmission link. WebCRC remainder replaces the appended string of 0s at the end of the data unit, and the final string would be 11100111 which is sent across the network. CRC Checker. The functionality of the CRC checker is similar to the CRC generator. When the string 11100111 is received at the receiving end, then CRC checker performs the modulo-2 division.

WebDec 27, 2024 · Cyclic redundancy check (CRC) is a common data transmission error detection technique commonly used in the data communication field. The transmit end calculates a check code for the data in a data frame based on a certain algorithm, appends the check code to the data frame, and sends the data frame to the receive end.
