Question

In the dividing circuit, the parity polynomial is obtained by the

(a) Quotient

(b) Remainder

(c) Dividend

(d) Divisor

I had been asked this question in examination.

This question is from Cyclic Codes and Linear Block Codes topic in chapter Channel Coding of Digital Communications

Answer 1

Correct answer is (b) Remainder

For explanation I would say: The parity polynomial is the remainder after diving by the generator polynomial it is available in the register after n shifts through the n-k stage feedback registers.
