**Image impedance** — is a concept used in electronic network design and analysis and most especially in filter design. The term image impedance applies to the impedance seen looking in to the ports of a network. Usually a two port network is implied but the concept… … Wikipedia

**image** — is an old word (13c) derived from Latin imago meaning ‘copy, likeness, picture’ and in all its meanings suggests a real or mental picture. Since the late 1950s it has been used by marketeers, advertisers, and political spin doctors to mean ‘a… … Modern English usage

**Derived functor** — In mathematics, certain functors may be derived to obtain other functors closely related to the original ones. This operation, while fairly abstract, unifies a number of constructions throughout mathematics. Contents 1 Motivation 2 Construction… … Wikipedia

**Derived set (mathematics)** — In mathematics, more specifically in point set topology, the derived set of a subset S of a topological space is the set of all limit points of S. It is usually denoted by S′. The concept was first introduced by Georg Cantor in 1872 and he… … Wikipedia
