Can you provide me the solution for following question.
1) Determine, using even parity throughout, the LRC / VRC block
check character generated from the following set of characters;
10000001 10000010 10000010 10000011 10000100. Calculate the
efficiency of this protocol if the efficiency is defined as:
(actual character bits/total number of bits)×100
2) Design a simple circuit to calculate the parity bit in a
seven bit character using XOR gates. Modify the circuit with an
extra XOR gate to select for even and odd parity. The circuit below
shows an example parity generator for four bits (D0, D1, D2, D3):
D0 D1 D2 D3 XOR XOR XOR XOR Parity X = 0 → Even parity X = 1 → Odd
parity mod 2(D0 + D1 + D2 + D3)
3) Show that the Hamming method can locate one parity error (use
the non matrix version)
