Shannon capacity
In
1949,
Claude Elwood Shannon and Warren Weaver wrote
The Mathematical Theory of Communication. (ISBN 0252725484) This founded the modern discipline of
information theory. Thus it is possible to measure the amount of information in a message.
Shannon's law
-
where
- C = bits per second - channel capacity,
- W = frequency - bandwidth,
- S/N = signal-to-noise ratio,
shows that there is a theoretical maximum amount of information that can be transmitted over a
bandwidth-limited carrier in the ever-present background
noise.
