1. Consider a CRC code with generator G=10011. Suppose that the data word is D=1010101010. What is the codeword (data followed by CRC bits) that the sender will transmit?

2. Consider a CRC code with generator polynomial g(x) = x 3 + 1. Can this generator detect any single-bit error? Can it also detect any odd number of bit errors? Explain your answers.
