Mountain View, California, United … 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…

Webb22 dec. 2024 · First, Shannon came up with a formula for the minimum number of bits per second to represent the information, a number he called its entropy rate, H. This number quantifies the uncertainty involved in determining which message the source will generate.
