The Nyquist theorem … Webb1 Theory 1.1 The Nyquist-Shannon sampling theorem The Nyquist theorem describes how to sample a signal or waveform in such a way as to not lose information. Suppose that we have a bandlimited signal X(t). Bandlimited means that if we were to take the Fourier transform of this signal, X^(f) = FfX(t)g, there would be a certain f

The sampling theory of Shannon can be generalized for the case of nonuniform sampling, that is, samples not taken equally spaced in time. The Shannon sampling theory for non-uniform sampling states that a band-limited signal can be perfectly reconstructed from its samples if the average sampling rate … Visa mer The Nyquist–Shannon sampling theorem is a theorem in the field of signal processing which serves as a fundamental bridge between continuous-time signals and discrete-time signals. It establishes a sufficient condition … Visa mer When $${\displaystyle x(t)}$$ is a function with a Fourier transform $${\displaystyle X(f)}$$: the Visa mer Poisson shows that the Fourier series in Eq.1 produces the periodic summation of $${\displaystyle X(f)}$$, regardless of $${\displaystyle f_{s}}$$ and $${\displaystyle B}$$. … Visa mer Sampling is a process of converting a signal (for example, a function of continuous time or space) into a sequence of values (a function of discrete time or space). Visa mer When there is no overlap of the copies (also known as "images") of $${\displaystyle X(f)}$$, the $${\displaystyle k=0}$$ term of Eq.1 can be recovered by the … Visa mer The sampling theorem is usually formulated for functions of a single variable. Consequently, the theorem is directly applicable to … Visa mer As discussed by Shannon: A similar result is true if the band does not start at zero frequency but at some higher value, and can be proved by a linear translation … Visa mer Webbshannon (sample) Arguments sample A vector of relative abundance data, typically a single column in a matrix Value Returns a single number indicating the amount of biodiversity in the tested sample Note Use apply functions to calculate Shannon's index for all samples in a matrix Author (s) Alexandra Linz Examples

Finally, we note that the relative diversities for our four samples are sensitive to sampling completeness, even after standardization (Fig. 5).
