The sampling theorem proves that an analog signal can be retrieved without errors and distortions from the sampling values — and outlines how this is done. The number of sampling values obtained per second must be at least twice as great as the highest frequency occurring in the original signal.

WebbShannon's channel coding theorem addresses how to encode the data to overcome the effect of noise. 2.4.1 Source Coding Theorem. The source coding theorem states that "the number of bits required to uniquely describe an information source can be approximated to the information content as closely as desired." WebbShannon’s well-known original formulation was in bits per second: C= Wlog 2 1 + P N bits/s: The difference between this formula and (1) is essentially the content of the sampling theorem, often referred to as Shannon’s theorem, that the number of independent samples that can be put through a channel of bandwidth Whertz is 2Wsamples per second.
