WebAn important class of prefix codes is the class of Huffman codes [14].The key idea behind the Huffman code is to represent a symbol from a source alphabet by a sequence of bits of length being proportional to the amount of information conveyed by the symbol under consideration, that is, L k ≅ −log(p k).Clearly, the Huffman code requires knowledge of … WebDec 1, 2014 · 1. yes yes I know how Huffman works but I cannot understand how you get out the code word for extended huffman. – user1930901.
