    Quick theory overview:
  • The syndrome is formed by shifting the entire received vector into the syndrome register.

    Procedure:
  • Initially, the syndrome register contents are 0 0 0. The right most bit of the received vector is given as the input to the circuit. This can be seen in the Simulation area as well as in the table in Observations.
  • Observe the contents of the syndrome register after every shift by clicking on Next.
  • The syndrome computation will be completeded after seven shifts, resulting in the register content being the syndrome.


Observe the computation of syndrome for the received vector 0010110 of the (7, 4) cyclic code with the generator polynomial g(x)=1+x+x3.
