WebbUnfortunately, Shannon–Fano coding does not always produce optimal prefix codes; the set of probabilities {0.35, 0.17, 0.17, 0.16, 0.15} is an example of one that will be assigned non-optimal codes by Shannon–Fano coding. Fano's version of Shannon–Fano coding is used in the IMPLODE compression method, which is part of the ZIP file format. [10] WebbMoreover, Shannon-Fano code can be constructed in several ways yielding different codes with different efficiencies. Exercise 1: The source of information A generates the symbols {A0, A1, A2, A3 and A4} with the …
