Cyclic Redundancy Check (CRC) A (256, 240) CRC code implies you take a frame of 240 data hits and you add a 16- bit PCs, such that the frame now contains 256 bits. EXAMPLE: Given the characteristic polynomial X" +1 = 1001, Length = 1+1, n-3. And the data = 11010101. To calculate the data that will be transmitted add no's to the data and divide by the characteristic polynomial X3 +1 = 1001 (EX-OR used in division) Dara 1001 11010101000 1001 1000 UOL 1101 1001 1000 Remainder 1001 100 Data transmited - 11010101100 Question 1 A digital communication system employs a CRC. The following block of data isto be transmitted 100110. Give then the characteristic polynomial toner +1.
