WebbShannon–Fano Algorithm The example shows the construction of the Shannon code for a small alphabet. The five symbols which can be coded have the following frequency: All … WebbExample 1: Given five symbols A to E with their frequencies being 15, 7, 6, 6 & 5; encode them using Shannon-Fano entropy encoding. Solution: Step1: Say, we are given that there are five symbols (A to E) that can occur in a source with their frequencies being 15 7 6 6 and 5. First, sort the symbols in decreasing order of frequency.
