Question - 1

Consider the following group of bits along with odd parity LRC bits is 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.

 

Solution

            Given group of bits

            10101110  11001101  10101010  11110000

                Converts this group of bit in to LRC

               

LRC

            10000110

Second bit from left shouldn't be one? 

could you explain this assignment plzzzzzz

1) how to find the polynomial?

2) how we calculate or identified LRC bits lost?

x^5+x^2+1

This equation has x^5 so 1 is written than it don't have x^4 a 0 is written again 0 for x^3 than x^2 is in the equation so a 1 is written than 0 for x and 1 for the constant as a constant is in the equation finally 100101

2. arrange 32 bits in 4x4 matrix than sum each column. for odd parity if answer of a bit is even add 1 else 0. For even parity if answer is odd add 1 else 0

Tariq sb you have pasted 2 different solutions. which one is correct?
