Q:Question:entropy of the source. 2. What is the minimum required average code word length to represent this source for error-free reconstruction? 3. Design a Huffman code for the source and compare the average length of the Huffman code with the entropy of the source. 4. Design a Huffman code for the second extension of the source (take two letters at a time). What is the average code word length? What is the average required binary letters per each
