Q:Question:with corresponding probabilities {0.1,0.2,0.3,0.4}. 1) Find the entropy of the source. 2) What is the minimum required average code length to reconstruct this source error-free? 3) Design a Huffman code for the source and compare the average length of the Huffman code with the source entropy. 4) Design a Huffman code for the source obtained by grouping two symbols at a time (second extension of the source). What is the average word length?A:Answer:See a step by step answer
