Shannon fano with the lempel ziv welsh algorithm, Computer Graphics

Assignment Help:

Question:

(a) A statistical encoding algorithm is being considered for the transmission of a large number of long text files over a public network. Part of the file content is as follows:

Assumption : empty spaces are taken into consideration.

Using the Shannon - Fano algorithm compute the following:

i) the average number of bits per codeword
ii) the entropy of the source
iii) the minimum number of bits required assuming fixed-length codeword

iv) the compression ratio based on this algorithm if we assume an ASCII of 8 bits representation

Support your answers with a Shannon tree and show necessary calculations for each part of the question.

(b) How do you compare the Shannon Fano with the Lempel Ziv Welsh (LZW) Algorithm?
