International Encyclopedia of Systems and Cybernetics

2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

CHANNEL CAPACITY 2)

← Back

The maximum rate (expressed as the number of information units per second) at which a channel can transmit messages with minimal distorsion.

According to C. SHANNON: "If the source is of a simple type, releasing symbols of equal length (as in the case of a teletype for example), if in this source each chosen symbol represents s information bits (freely chosen from 2 symbols) and finally the channel may transmit, let us say, n symbols per second, the capacity C of the channel is then defined as being ns bits per second" (1949).

This is of course a strictly quantitative and numerical measurement, once the needed energy has been used to create the signals. In R.N. ADAMS words: "The channel capacity of a telephone circuit refers to the fact that the physical composition of the circuit can receive only a finite amount of energetic activity over a given period of time" (1988, p.84).
