  1. Há 4 dias · Shannon–Hartley theorem. v. t. e. Information theory is the mathematical study of the quantification, storage, and communication of information. [1] . The field was originally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s.

  2. 30 de abr. de 2024 · In 1948 Shannon published “A Mathematical Theory of Communication,” which built on the foundations of other researchers at Bell Labs such as Harry Nyquist and R.V.L. Hartley. Shannon’s paper, however, went far beyond the earlier work.

  3. Há 2 dias · Fundamental theoretical work in telecommunications technology was developed by Harry Nyquist and Ralph Hartley in the 1920s. Information theory, as enunciated by Claude Shannon in 1948, provided a firm theoretical underpinning to understand the trade-offs between signal-to-noise ratio, bandwidth, and error-free transmission in the ...

    Há 2 dias · In 1928 the thermal noise in a resistor was first measured by John B. Johnson, for which Harry Nyquist provided the theoretical analysis; this is now termed Johnson noise. During the 1920s, the one-time pad cipher was invented by Gilbert Vernam and Joseph Mauborgne at the laboratories.

  5. 15 de mai. de 2024 · In 1932, Harry Nyquist, a Swedish-American electrical engineer, published his regeneration (or feedback) theory, which is a criterion for determining the stability of feedback systems based on their frequency response, known as the Nyquist criterion.

  6. 7 de mai. de 2024 · Information theory is the scientific study of the quantification, storage, and communication of information. The field was fundamentally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s.

  7. 14 de mai. de 2024 · Note: The name Nyquist--Shannon sampling theorem honors Harry Nyquist (1889--1976) and Claude Shannon (1916--2001), known as "the father of information theory". The theorem was also discovered independently by Edmund Taylor Whittaker (1873--1956), by Vladimir Kotelnikov (1908--2005), and by others.
