"A Mathematical Theory of Communication" is an article by
Bell System Technical Journal in 1948.[1][2][3][4] It was renamed The Mathematical Theory of Communication in the book of the same name,[5]
a small but significant title change after realizing the generality of this work.
Description
The article was the founding work of the field of
ISBN 0-252-72548-4). The book contains an additional article by Warren Weaver
, providing an overview of the theory for a more general audience. Shannon's article laid out the basic elements of communication:
- An information source that produces a message
- A transmitter that operates on the message to create a signalwhich can be sent through a channel
- A channel, which is the medium over which the signal, carrying the information that composes the message, is sent
- A receiver, which transforms the signal back into the message intended for delivery
- A destination, which can be a person or a machine, for whom or which the message is intended
It also developed the concepts of
information entropy and redundancy, and introduced the term bit (which Shannon credited to John Tukey) as a unit of information. It was also in this paper that the Shannon–Fano coding technique was proposed - a technique developed in conjunction with Robert Fano
