Webb12. Explain Shannon-Fano coding. An efficient code can be obtained by the following simple procedure, known as Shannon – Fano algorithm. Step 1: List the source symbols in order of decreasing probability. Step 2: Partition the set into two sets that are as close to equiprobable as possible, and sign 0 to the upper set and 1 to the lower set. WebbShannon–Fano method, proposed independently by Claude Shannon and Robert Fano in the late 1940s ([Shannon 48] and [Fano 49]). It generally produces better codes, and like the Shannon–Fano method, it produces the best variable-length codes when the probabilities of the symbols are negative powers of 2.
