Question No. 2                                                                                                                               

Calculate the Hamming pairwise distance among the following code words. Also find the minimum Hamming distance.

00000,01011

 pairwise distance=3

00000,01010

pairwise distance=2

00000,10101

 pairwise distance=3

D    00000,11110

pairwise distance=4

Minumum Hamming Distance is 2
