Webb23 mars 2024 · Claude Elwood Shannon (30 avril 1916 à Gaylord, Michigan - 24 février 2001) est un ingénieur électricien et mathématicien américain. Il est l'un des pères, si ce n'est le père fondateur, de la théorie de l'information. Son nom est attaché à un célèbre " schéma de Shannon " très utilisé en sciences humaines, qu'il a constamment ... WebbShannon (1948) laid the groundwork for information theory in his seminal work. However, Shannon's theory is a quantitative theory, not a qualitative theory. Shannon's theory tells you how much “stuff” you are sending through a channel, but it does not care if it is a cookie recipe or the plans for a time machine.

It is the fundamental maximum transmission capacity that can be achieved using the basic resources available in the channel, without going into details of coding scheme or modulation. It is the best performance limit that we hope to achieve for that channel.
