WebbShannon Index (H) = - ∑ 1 ln s i p i p i = Simpson Index (D) = ∑ 1 2 1 s i p i = The Shannon index is an information statistic index, which means it assumes all species are represented in a sample and that they are randomly sampled. Can you point out any problems in these assumptions? In the Shannon index, p is the proportion (n/N) of ...

Now, if 1 T = f s > 2 B, where B is the band-limit of X ( f), then we can reconstruct the continuous time signal as:
Webb26 apr. 2013 · Shannon’s law is stated as shown below: C = B log2< (1 + S/N) where: C is the highest attainable error-free data speed in bps that can be handled by a communication channel. B is the bandwidth of the channel in hertz. S is the average signal power received over the bandwidth calculated in watts (or volts squared).

WebbIf the SNR is 20 dB, and the bandwidth available is 4 kHz, which is appropriate for telephone communications, then C = 4000 log 2 (1 + 100) = 4000 log 2 (101) = 26.63 kbit/s. Note that the value of S/N = 100 is equivalent to the SNR of 20 dB.

Since the variance of a Gaussian process is equivalent to its power, it is conventional to call this variance the noise power. 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.
