CRC Error Detection: Consider a data block: 11100011001111 to which a CRC FCSsequence needs to be attached and then transmitted. The predetermined divisor code(pattern) is 111010101. Answer the following questionsa.
i) What is the value of âkâ?ii) What is the value of ânâ?
b.
i) Represent the data block and the divisor code as polynomialsii) Calculate the FCS sequence using polynomial long division asdiscussed in the lecture notes and mention the transmitted frame (data +FCS)?
c.
i) Sketch the CRC architecture using XOR gates and shift registers. Showonly relevant connections.ii) Calculate the contents of the shift register after the firstthree (3) data bits are applied.
