Shannon's source coding theorem
Webb22 maj 2024 · The Source Coding Theorem states that the average number of bits needed to accurately represent the alphabet need only to satisfy H ( A) ≤ B ( A) ¯ ≤ H ( A) + 1 … Webb27 juli 2024 · This is precisely the non-intuitive content of Shannon’s channel coding theorem. A similar result was derived by von Neumann where he showed that as long as the basic gates used in constructing a computer are more reliable than a certain threshold, one could make a highly precise computer.

WebbIn this case, Shannon’s theorem says precisely what the capacity is. It is 1 H(p) where H(p) is the entropy of one bit of our source, i.e., H(p) = plog 2p (1 p)log 2(1 p). De nition 1.
