Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the … Wikipedia
Sampling design — In the theory of finite population sampling, a sampling design specifies for every possible sample its probability of being drawn.Mathematically, a sampling design is denoted by the function P(S) which gives the probability of drawing a sample S … Wikipedia
Finite impulse response — A finite impulse response (FIR) filter is a type of a digital filter. The impulse response, the filter s response to a Kronecker delta input, is finite because it settles to zero in a finite number of sample intervals. This is in contrast to… … Wikipedia
Sampling fraction — In sampling theory, sampling fraction is the ratio of sample size to population size.The formula for the sampling fraction is = n/N where n is the sample size and N is the population size. If the sampling fraction is less than 5%, then ignore the … Wikipedia
Sampling equiprobably with dice — An illustrative example of how to compute with the probabilities associated to dice, as well as the analysis of algorithms, is the following problem. Suppose you have a group of 19 individuals and an ordinary six sided die. Your task is to use… … Wikipedia
Nyquist–Shannon sampling theorem — Fig.1: Hypothetical spectrum of a bandlimited signal as a function of frequency The Nyquist–Shannon sampling theorem, after Harry Nyquist and Claude Shannon, is a fundamental result in the field of information theory, in particular… … Wikipedia
Pseudo-random number sampling — or non uniform pseudo random variate generation is the numerical practice of generating pseudo random numbers that are distributed according to a given probability distribution. Methods of sampling a non uniform distribution are typically based… … Wikipedia
Poisson sampling — In the theory of finite population sampling, Poisson sampling is a sampling process where each element of the population that is sampled is subjected to an independent Bernoulli trial which determines whether the element becomes part of the… … Wikipedia
Bernoulli sampling — In the theory of finite population sampling, Bernoulli sampling is a sampling process where each element of the population that is sampled is subjected to an independent Bernoulli trial which determines whether the element becomes part of the… … Wikipedia
Survey sampling — In statistics, survey sampling is random selection of a sample from a finite population. It is an important part of planning statistical research and design of experiments. Sophisticated sampling techniques that are both economical and… … Wikipedia
Chemotaxis — is the phenomenon in which somatic cells, bacteria, and other single cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by … Wikipedia
