0. In CRC checksum method, assume that given frame for transmission is 1101011011 and the generator polynomial is G(x) = x4 + x + 1. After implementing CRC encoder, the encoded word sent from sender side is _____.

  • Option : A
  • Explanation :
    Given frame for transmission is 1101011011 and generator polynomial is G(x) = x4 + x + 1 i.e. 10011. We have to append 4 0's (1 0's less then divisor according to CRC):

    We have to append 1110 to the frame. Now our frame for transmission is 11010110111110. So, option (A) is correct.
