Question in image (its about cyclic redundancy check)
Task 2: Error Detection and Correction: Cyclic Redundancy Check Consider the Cyclic Redundancy Check (CRC) example shown in your lecture. Suppose that the 4-bit generator (G) is 1001, that the data payload (D) is 10011111 and that r=3. a) What are the CRC bits (R) associated with the data payload of D = 10011111, given that r=3? b) Add the obtained CRC bits with the payload and check whether the receiver has detected an error or not?
