Webb1 Hereafter we shall always express information capacity in binary units (bits) per sample. Shannon’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, that the number of WebbShannon Capacity definition: Synonym of Shannon limit. .

WebbShannon's definition of entropy, when applied to an information source, can determine the minimum channel capacity required to reliably transmit the source as encoded binary digits. Shannon's entropy measures the information contained in a message as opposed to the portion of the message that is determined (or predictable). WebbWorked Example Problems Information Theory and Coding: Example Problem Set 1 Let X and Y represent random variables with associated probability distributions p(x) and p(y), respectively. They are not independent. Their conditional probability distributions are p(x y) and p(y x), and their joint probability distribution is p(x,y). 1.
