Shannon third theorem
The Shannon–Hartley theorem states the channel capacity , meaning the theoretical tightest upper bound on the information rate of data that can be communicated at an arbitrarily low error rate using an average received signal power through an analog communication channel subject to additive white … 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 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 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.

The sampling theorem specifies the minimum-sampling rate at which a continuous-time signal needs to be uniformly sampled so that the original signal can be completely recovered or reconstructed by these samples alone. This is usually referred to as Shannon's sampling theorem in the literature.
WebbThe theorem establishes Shannon's channel capacity for such a communication link, a bound on the maximum amount of error-free digital data (that is, information) that can be transmitted with a specified bandwidth in the presence of the noise interference, assuming that the signal power is bounded, and that the Gaussian noise process is … WebbThis theorem is the basis for error correcting codes using which we can achieve error-free transmission. Again, Shannon only specified that using ‘good’ coding mechanisms, we can achieve error-free transmission, but he did not specify …
