Calculate checksum for T = 11000101 and G = 1100

Explanation

  • Here, transmitted frame, T in polynomial form

=

= + 1

  • The generator frame, G in polynomial form

=

=

  • Dividing Transmitted frame, T by Generator frame, G
  • We will get reminder in polynomial form x2 + 1.
  • So, data bits will be 101
  • Based on Cyclic Redundancy Check (CRC) we can find checksum which is remainder of the division. So 101 will be the checksum for the given transmitter and generator frame.
