WebbÀ partir des années 1960, le théorème d'échantillonnage est souvent appelé théorème de Shannon, du nom de l'ingénieur qui en a publié la démonstration en posant les bases de la théorie de l'information chez Bell Laboratories en 1949. Shannon's theorem shows how to compute a channel capacity from a statistical description of a channel, and establishes that given a noisy channel with capacity and information transmitted at a line rate , then if there exists a coding technique which allows the probability of error at the receiver to be made … Visa mer In information theory, the Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise. It is an application of the Visa mer 1. At a SNR of 0 dB (Signal power = Noise power) the Capacity in bits/s is equal to the bandwidth in hertz. 2. If the SNR is 20 dB, and the bandwidth available is 4 kHz, which is appropriate … Visa mer • On-line textbook: Information Theory, Inference, and Learning Algorithms, by David MacKay - gives an entertaining and thorough introduction to Shannon theory, including two proofs … Visa mer During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of … Visa mer Comparison of Shannon's capacity to Hartley's law Comparing the channel capacity to the information rate from Hartley's law, we can find the effective number of distinguishable levels M: Visa mer • Nyquist–Shannon sampling theorem • Eb/N0 Visa mer
