Teorema shannon hartley
During 1928, Hartley formulated a way to quantify information and its line rate (also known as data signalling rate R bits per second). This method, later known as Hartley's law, became an important precursor for Shannon's more sophisticated notion of channel capacity. See more 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 See more 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 for telephone communications, then C = 4000 log2(1 + 100) = 4000 log2 … See more • On-line textbook: Information Theory, Inference, and Learning Algorithms, by David MacKay - gives an entertaining and thorough introduction to Shannon theory, including two proofs of the noisy-channel coding theorem.

La teoria dei segnali è una teoria ingegneristica che studia e definisce le proprietà matematiche e statistiche dei segnali, definiti come funzioni matematiche del tempo: in generale, un segnale è una variazione temporale dello stato fisico di un sistema o di una grandezza fisica, come la tensione o l'intensità di corrente ...
