WebbStated by Claude Shannon in 1948, the theorem describes the maximum possible efficiency of error-correcting methods versus levels of noise interference and data corruption. Shannon's theorem has wide-ranging applications in both communications and data storage. This theorem is of foundational importance to the modern field of … WebbShannon entropy is a concept introduced from physical systems by Shannon to estimate the amount of information (Shannon, 1948 ), its calculation is given as follows, (4) Where l is the total number and pi is the probability of the situation i in the system.
