| Noah Webster | 1: [Adjective] Separate; distinct; disjunct. Discrete proportion is when the ratio of two or more pairs of numbers or quantities is the same, but there is not the same proportion between all the numbers; as 3:6::8:16, 3 bearing the same proportion to 6, as 8 does to 16. But 3 is not to 6 as 6 is to 8. It is thus opposed to continued or continual proportion, as 3:6::12:24.. | 2: [Adjective] Disjunctive; as, I resign my life, but not my honor, is a discrete proposition..

Common Expressions: discrete
| Expressions | Definition | ||
| Discrete category | Clearly, any class of objects defines a discrete category when augmented with identity maps. (references) | ||
| Discrete device | A discrete device is an electronic component with just one circuit element. The term is used to distinguish the component from integrated circuits and hybrid circuits, which are built from several circuit elements in one package. It typically refers to semiconductor devices. (references) | ||
| Discrete geometry | Discrete geometry or combinatorial geometry may be loosely defined as study of geometrical objects and properties that are discrete or combinatorial, either by their nature or by their representation; the study that does not essentially rely on the notion of continuity. (references) | ||
| Discrete group | In mathematics, a discrete group is a group G equipped with the discrete topology. With this topology G becomes a topological group. A discrete subgroup of a topological group G is a subgroup H whose relative topology is the discrete one. For example, the integers, Z, form a discrete subgroup of the reals, R, but the rational numbers, Q, do not. (references) | ||
| Discrete Hankel transform | In mathematics and statistics, the discrete Hankel transform acts on a vector of sampled data, where the samples are assumed to have been taken at points related to the zeroes of a Bessel function of fixed order; compare this to the case of the discrete Fourier transform, where samples are taken at points related to the zeroes of the sine or cosine function. Likewise, the discrete Hankel transform is related to the continuous Hankel transform just as the discrete Fourier transform is related to the continuous Fourier transform. (references) | ||
| Discrete Hartley transform | A discrete Hartley transform (DHT) is a Fourier-related transform of discrete, periodic data similar to the discrete Fourier transform (DFT), with analogous applications in signal processing etcetera. Its main distinction from the DFT is that it transforms real inputs to real outputs, with no intrinsic involvement of complex numbers. Just as the DFT is the discrete analogue of the continuous Fourier transform, the DHT is the discrete analogue of the continuous Hartley transform, introduced by R. V. L. Hartley in 1942. (references) | ||
| Discrete Laplace operator | In mathematics, the discrete Laplace operator is an analog of the continuous Laplace operator, defined so that it has meaning on a graph or a discrete grid. The discrete Laplace operator occurs in physics problems such as the Ising model and loop quantum gravity, as well as in the study of discrete dynamical systems. (references) | ||
| Discrete Lorentzian quantum gravity | In the theory of discrete Lorentzian quantum gravity, space itself is modeled by a lattice instead of a manifold. (references) | ||
| Discrete modelling | Discrete modelling is the discrete analogue of continuous modelling. In discrete modelling, discrete formulae are fit to data. A common method in this form of modelling is to use recurrence relations. (references) | ||
| Discrete number | A discrete number is an integer that can be stored and reproduced precisely. This is in contrast to a floating point integer, which cannot be stored and reproduced in its precise form. (references) | ||
| Discrete optimization | Discrete optimization is a branch of optimization in applied mathematics and computer science. (references) | ||
| Discrete proportion | Proportion where the ratio of the means is different from that of either couplet; as, 3:6::8:16, 3 bearing the same proportion to 6 as 8 does to 16. But 3 is not to 6 as 6 to 8. It is thus opposed to continued or continual proportion ; as, 3:6::12:24. Source: Webster's Revised Unabridged Dictionary. | ||
| Discrete quantity | That which must be divided into units, as number, and is opposed to continued quantity , as duration, or extension. Source: Webster's Revised Unabridged Dictionary. | ||
| Discrete signal | A discrete signal is a signal that has been sampled from a continuous signal. (references) | ||
| Discrete sine transform | The discrete sine transform (DST) is a Fourier-related transform similar to the discrete Fourier transform (DFT), but using only real numbers. It is equivalent to the imaginary parts of a DFT of roughly twice the length, operating on real data with odd symmetry (since the Fourier transform of a real and odd function is real and imaginary), where in some variants the input and/or output data are shifted by half a sample. (references) | ||
| Discrete spectrum | In mathematics and physics, discrete spectrum is a finite set or a countable set of eigenvalues of an operator. An operator acting on a Hilbert space is said to have a discrete spectrum if its eigenvalues cannot be changed continuously. If the spectrum of an operator is not discrete, we say that it is a continuous spectrum. (references) | ||
| Discrete symmetry | In theoretical physics, a discrete symmetry is a symmetry under the transformations of a discrete group - i.e. a topological group with a discrete topology whose elements form a finite or a countable set. (references) | ||
| Discrete system | A discrete system or discrete-time system, as opposed to a continuous-time system, is one in which the signals are sampled periodically. It is usually used to connote an analog sampled system, rather than a digital sampled system, which uses quantized values. (references) | ||
| Discrete time | Discrete time is non-continuous time. Sampling at non-continuous times results in discrete-time samples. For example, a newspaper may report the price of crude oil once every 24 hours. In general, the sampling period in discrete-time systems is constant, but in some cases non-uniform sampling is also used. (references) | ||
| Discrete valuation | For example, if A is the ring of integers, these properties are satisfied with ν(n) the largest value of k such that 2k divides n. (references) | ||
| Discrete valuation ring | In mathematics, a discrete valuation ring (DVR) is a particular kind of commutative ring that is a local ring, which satisfies conditions that in algebraic geometry come from non-singularity of a point on an algebraic curve. There are many examples that are not geometric in nature. (references) | ||
| Discrete wavelet transform | In numerical analysis and functional analysis, the discrete wavelet transform (DWT) refers to wavelet transforms for which the wavelets are discretely sampled. (references) | ||
| Irrational base discrete weighted transform | In mathematics, the irrational base discrete weighted transform (IBDWT) is a variant of the fast Fourier transform using an irrational base; it was developed by Richard Crandall (Reed College), Barry Fagin (Dartmouth College) and Joshua Doenias (NeXT Software) in the early 1990s using Mathematica. (references) | ||
| Modified discrete cosine transform | In MP3, the MDCT is not applied to the audio signal directly, but rather to the output of a 32-band polyphase quadrature filter (PQF) bank. The output of this MDCT is postprocessed by an alias reduction formula to reduce the typical aliasing of the PQF filter bank. Such a combination of a filter bank with an MDCT is called a hybrid filter bank or a subband MDCT. AAC, on the other hand, normally uses a pure MDCT; only the (rarely used) MPEG-4 AAC-SSR variant (by Sony) uses a four-band PQF bank followed by an MDCT. ATRAC uses stacked quadrature mirror filters (QMF) followed by an MDCT. (references) | ||
