Given a 10 bit sequence 1010011110 and a divisor of 1011, find the CRC and check your answer? Which of the following g(x) values guarantees that a single-bit error is caught? For each case, what is the error that cannot be caught?
a. x + 1 b. x3 c. 1




Given Sequence: 1010011110


We append 000 and divided by 1011


Code:
   1011)1010 011 1100 000   (1001001110
                            1011
                        ________                                         
                                    1011
                                     1011
                                 ________
                                               1100
                                                  1011
                                               _________
                                                1110
                                                 1011
                                               _________
                                                     1010
                                                      1011
                                            ______________
                                                             010        ---Remainder
So,CRC encoded sequence is 10100111100010
Check;
Code:
   1011)1010  011 1100 010    (10010001100
                             1011
                          ------------
                                   1011
                                    1011
                                   -------------
                                              1100
                                                 1011
                                              --------------
                                                1110
                                                1011
                                               -----------------
                                                   1011
                                                    1011
                                                  -----------
                                                      000  --Remainder
Check that remainder is 0.
