5. In a CRC error-detection scheme, choose P(x) = x^4 x 1.a. Encode the bits 10101001011 and confirm. (5 marks)b. Introduce an error pattern 000010100001000, i.e., invert the digit in the codeword where it appears in the error pattern sequence and see if the error can be detected. (3 marks)c. Introduce an error pattern 000101110000000 and see if the error can be detected. What can be deduced? (6 marks)

What is CRC-4 (Cyclic Redundancy Check 4)?

How is CRC calculated? - TimesMojo

Explain the answer.5. The cyclic redundancy check (CRC) code is used in some link-layer protocols to generate a checksum for error detection. Suppose the following generator polynomial is used in the CRC code: G(x) = x^10 x^9 x^8 x^7 x^6 x^4 x^3 1. How many check bits does it generate? A. 8 bits B. 10 bits C. 11 bits D. 16 bits
