WebAug 11, 2024 · Accordingly, when a data is encoded with Huffman Coding, we get a unique code for each symbol in the data. For example the string “ABC” occupies 3 bytes without any compression. Let’s assume while the character A is given the code 00, the character B is given the code 01, the character C is given the code 10 as the result of encoding. Web(b) Huﬀman code is optimal code and achieves the entropy for dyadic distribution. If the distribution of the digits is not Bernoulli(1 2) you can compress it further.
