Unformatted text preview: d. What is the minimum number of bit errors that cause a detection failure? 3.60 Let g(x)=x 3 +x+1. Consider the information sequence 1001. a. Find the codeword corresponding to the preceding information sequence. b. Suppose that the codeword has a transmission error in the first bit. What does the receiver obtain when it does its error checking? 3.62 Suppose a header consists of four 16-bit words: (11111111 11111111, 11111111 00000000, 11110000 11110000, 11000000 11000000). Find the internet checksum for this code. 3.63 Let g 1 (x) = x + 1 and let g 2 (x) = x 3 + x 2 + 1. Consider the information bits (1,1,0,1,1,0). a. Find the codeword corresponding to these information bits if g 1 (x) is used as the generating polynomial. b. Find the codeword corresponding to these information bits if g 2 (x) is used as the generating polynomial....
