In CRC checksum method, assume that given frame for transmission is 11010111011 and the generator polynomial is G(x) = x⁴ + x + 1. After implementing CRC encoder, the encoded word sent from sender side is ____ .

Correct answer: (A) 11010110111110
Explanation
Note: the frame as printed (11010111011) actually gives the codeword 110101110111011, which matches no option; the keyed answer corresponds to the frame 1101011011 used in the book's solution. The generator G(x) = x⁴ + x + 1 is 10011. Append 4 zeros to the message 1101011011 to get 11010110110000 and divide by 10011; the remainder is 1110, so the transmitted message is 11010110111110.
