Question: A discrete memoryless source outputs letters from the alphabet 0, 1, 2, 3 with respective probabilities 0.1, 0.35, 0.25, 0.3. a) What is the information

A discrete memoryless source outputs letters from the alphabet 0, 1, 2, 3 with respective

probabilities 0.1, 0.35, 0.25, 0.3.

a) What is the information content of each letter?

b) What is the average information content of the source output?

c) How many bits per letter are required to transmit the DMS output without source coding?

d) Use the Huffman procedure to assign binary codewords to the letters and calculate the

resultant source coder average output bit rate.

e) What is the bit sequence required to communicate the DMS output symbol sequence 1, 3, 0, 1,

3, 1, 2, 0, 2, 1 using uncoded and Huffman coding procedures?
