In a 5 bit CRC error detecting scheme, assume we choose the generating bit sequence as 11011.
a) Encode the bit stream 11001010011.
b) Assume the channel introduces two errors such that the first and fourth bits are flipped. What pattern is received? Can the error be detected?
c) Now assume three errors occur such that the first, third and fifth bits are flipped. What pattern is received and can the error be detected?
