Question Five i. Assume a memoryless source with alphabet A={a1,a2,a3,a4} having probability P(a1)=1/2,P(a2)=1/4,P(a3)=P(a4)=1/8. Find its efficiency for FIFO and FIVO ii. Consider a DMS with source probabilities {0.20,0.20,0.15,0.15,0.10,0.10, 0.05,0.05} a. Determine an efficient fixed length code for the source b. Determine an efficient of Huffman code for this source c. Compare i and ii and comment
