**Discrete frequency** — is defined as the frequency with which the samples of a discrete sinusoid occur. Just as in its continuous time counterpart (see frequency), the discrete time signal has a time axis, conventionally denoted by n . The time variable n , however,… … Wikipedia

**Interval arithmetic** — Interval arithmetic, also called interval mathematics , interval analysis , and interval computation , is a method in mathematics. It has been developed by mathematicians since the 1950s and 1960s as an approach to putting bounds on rounding… … Wikipedia

**Discrete-time Fourier transform** — In mathematics, the discrete time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the DTFT , of the… … Wikipedia

**Discrete 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… … Wikipedia

**Discrete event simulation** — In discrete event simulation, the operation of a system is represented as a chronological sequence of events. Each event occurs at an instant in time and marks a change of state in the system [1]. For example, if an elevator is simulated, an… … Wikipedia

**Discrete phase-type distribution** — The discrete phase type distribution is a probability distribution that results from a system of one or more inter related geometric distributions occurring in sequence, or phases. The sequence in which each of the phases occur may itself be a… … Wikipedia

**Discrete mathematics** — For the mathematics journal, see Discrete Mathematics (journal). Graphs like this are among the objects studied by discrete mathematics, for their interesting mathematical properties, their usefulness as models of real world problems, and their… … Wikipedia

**Discrete time** — This article is about discrete time in signal processing. For discrete time in quantum physics, see quantum time. Discrete time is the discontinuity of a function s time domain that results from sampling a variable at a finite interval. For… … Wikipedia

**Discrete 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… … Wikipedia
