WebbClaude Shannon first proposed the information theory in 1948. The goal was to find the fundamental limits of communication operations and signal processing through an operation like data compression. It is a theory that has been extrapolated into thermal physics, quantum computing, linguistics, and even plagiarism detection. During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the context of the telegraph as a communications system. At the time, these concepts were powerful breakthroughs individually, but they were not part of a comprehensive theory. In the 1940s, Claude Shannon developed the concept of channel capacity, based in part on the ideas of Nyquist and Hartley, and then formula… chuck stone

"Webb6 sep. 2024 · Shannon calculated that the entropy of the English language is 2.62 bits per letter (or 2.62 yes-or-no questions), far less than the 4.7 you’d need if each letter appeared randomly. Put another way, patterns reduce uncertainty, which makes it possible to communicate a lot using relatively little information. " - Shannon information limit

WebbIn this case, the Set Shaping Theory SST is used, a new method that is revolutionizing information theory. This theory studies the one-to-one functions f that transform a set of strings into a set of equal size made up of strings of greater length. With this method, we get the following limit: N2H (Y)+ source information≈NH (X) with f (X)=Y ... WebbMeaning of Shannon information capacity In electronic communication channels the information capacity is the maximum amount of information that can pass through a channel without error, i.e., it is a measure of channel “goodness.” The actual amount of information depends on the code— how information is represented.

It is mathematically more suitable. Many of the limiting operations are simple in terms of the loga-rithm but would require clumsy restatement in terms of the number of possibilities.

Webb17 feb. 2015 · Shannon's formula C = 1 2 log (1+P/N) is the emblematic expression for the information capacity of a communication channel. Hartley's name is often associated with it, owing to Hartley's rule: counting the highest possible number of distinguishable values for a given amplitude A and precision ±Δ yields a similar expression C′ = log (1+A/Δ).
