**Bilinear time–frequency distribution** — Bilinear time–frequency distributions, or quadratic time–frequency distributions, arise in a sub field field of signal analysis and signal processing called time–frequency signal processing, and, in the statistical analysis of time series data.… … Wikipedia

**Bilinear transform** — The bilinear transform (also known as Tustin s method) is used in digital signal processing and discrete time control theory to transform continuous time system representations to discrete time and vice versa. The bilinear transform is a… … Wikipedia

**Bilinear interpolation** — In mathematics, bilinear interpolation is an extension of linear interpolation for interpolating functions of two variables on a regular grid. The key idea is to perform linear interpolation first in one direction, and then again in the other… … Wikipedia

**Projective transformation** — A projective transformation is a transformation used in projective geometry: it is the composition of a pair of perspective projections. It describes what happens to the perceived positions of observed objects when the point of view of the… … Wikipedia

**Möbius transformation** — Math. a map of the complex plane to itself in which a point z is mapped to a point w by w = (az + b)/(cz + d), where a, b, c, and d are complex numbers and ad bc does not equal zero. Also called bilinear transformation, linear fractional… … Universalium

**Möbius transformation** — Not to be confused with Möbius transform or Möbius function. In geometry, a Möbius transformation of the plane is a rational function of the form of one complex variable z; here the coefficients a, b, c, d are complex numbers satisfying ad − … Wikipedia

**Natural transformation** — This article is about natural transformations in category theory. For the natural competence of bacteria to take up foreign DNA, see Transformation (genetics). In category theory, a branch of mathematics, a natural transformation provides a way… … Wikipedia
