![Q1. How does a single-bit error differ from a burst error? In a block code, a dataword is 20 bits and the
corresponding codeword is 25 bits. What are the values of k, r, and n according to the definitions in the
text? How many redundant bits are added to each dataword?
Q2. In CRC, if the dataword is 5 bits and the codeword is 8 bits, how many Os need
to be added to the dataword to make the dividend? What is the size of the
remainder? What is the size of the divisor?
Q3. Given the dataword 10100110101 and the divisor 10101, show the generation of
the CRC codeword at the sender site (using binary division). Now convert the dataword and divisor in
polynomials and show the generation of the CRC codeword at the sender site.
