This theorem is the basis for error correcting codes using which we can achieve error-free transmission. cub foods coon rapids minnesota

Webb24 jan. 2024 · Shannon Fano Algorithm is an entropy encoding technique for lossless data compression of multimedia. Named after Claude Shannon and Robert Fano, it assigns a code to each symbol based on their probabilities of occurrence. It is a variable-length encoding scheme, that is, the codes assigned to the symbols will be of varying lengths.
