81Discrete symmetry — A discrete symmetry is a symmetry that describes non continuous changes in a system. For example, a square possesses discrete rotational symmetry, as only rotations by multiples of right angles will preserve the square s original appearance.… …
82Discrete device — A discrete device (or discrete component) is an electronic component with just one circuit element, either passive (resistor, capacitor, inductor) or active (transistor or vacuum tube), other than an integrated circuit. Several discrete devices… …
83Discrete Poisson equation — In mathematics, the discrete Poisson equation is the finite difference analog of the Poisson equation. In it, the discrete Laplace operator takes the place of the Laplace operator. The discrete Poisson equation is frequently used in numerical… …
84Discrete Fourier series — A Fourier series is a representation of a function in terms of a summation of an infinite number of harmonically related sinusoids with different amplitudes and phases. The amplitude and phase of a sinusoid can be combined into a single complex… …
85Discrete orthogonal polynomials — In mathematics, a sequence of discrete orthogonal polynomials is a sequence of polynomials that are pairwise orthogonal with repect to a discrete measure. Examples include the discrete Chebyshev polynomials, Charlier polynomials, Krawtchouk… …
86Discrete weighted transform — In mathematics, the discrete weighted transform (DWT) is a variation on the discrete Fourier transform over arbitrary fields involving weighting the input before transforming it.[1] References ^ Crandall, Richard; Fagin, Barry (1994), Discrete… …
87Discrete Event System Specification — DEVS (de l anglais Discrete Event System Specification) est un formalisme modulaire et hiérarchique pour la modélisation, la simulation et l analyse de systèmes complexes qui peuvent être des systèmes à événements discrets décrits par des… …
88Discrete two-point space — In topology, a branch of mathematics, a discrete two point space is the simplest example of a totally disconnected discrete space. The points can be denoted by the symbols 0 and 1. Any disconnected space has a continuous mapping onto the… …
89Discrete Chebyshev polynomials — Not to be confused with Chebyshev polynomials. In mathematics, discrete Chebyshev polynomials, or Gram polynomials, are a type of discrete orthogonal polynomials used in approximation theory, introduced by Pafnuty Chebyshev (1864) and… …
90Discrete Distribution — The statistical or probabilistic properties of observable (either finite or countably infinite) pre defined values. Unlike a continuous distribution, which has an infinite number of outcomes, a discrete distribution is characterized by a limited… …
