• Polynomials

Assignment

Question - 1
Consider the following groups of bits (G1 to G8) along with Even parity LRC bits are sent to the receiver, but due to transmission impairments some bits of LRC are lost. You are required to identify the lost LRC bits and complete the given table:

Groups
G1 G2 G3 G4 G5 G6 G7 G8
1 1 1 0 1 0 1 1
1 1 0 1 1 1 0 1
1 0 1 0 1 1 1 0
0 1 0 0 1 1 0 1
LRC bits 1 ? ? 1 ? 1 ? ?

Question – 2

Find the Polynomials equivalent for the binary group bits given in the following table:

Binary Polynomial Equivalent
1011
11001
101100
