Cyclic Redundancy Check (CRC) A (256,240) CRC code implies you take a frame al 240 datu bils and you add 16- bit FCS, such that the frame now contains 256 bits. EXAMPLE: Given the characteristic polynomialX 1-1001 Longth=n+1.n=3 And the dulu = 11010101 To calculate the data that will be transmitted add nu's to the data and divide by the characteristic polynomial X-1 - 1001 (EX-OR used in division) Data 1001 1010101000 1001 1000 TO 1101 1001 1000 1001 Romans Data transmited = 11010101100 Question 1 A digital communication system employs a CRC.
