91n-gram — Not to be confused with engram. In the fields of computational linguistics and probability, an n gram is a contiguous sequence of n items from a given sequence of text or speech. The items in question can be phonemes, syllables, letters, words or …
92фильтр нижних частот — Ндп. задерживающий низкочастотный фильтр Электрический частотный фильтр, имеющий полосу пропускания ниже заданной частоты среза и полосу задерживания для более высоких частот [ГОСТ 24375 80] фильтр нижних частот Фильтр, пропускающий сигналы с… …
93преобразователь частоты — [IEV number 151 13 43] [IEV number 313 03 06] преобразователь частоты Преобразователь электрической энергии переменного тока, который преобразует электрическую энергию с изменением частоты [ОСТ 45.55 99] EN frequency converter electric energy… …
94Group (mathematics) — This article covers basic notions. For advanced topics, see Group theory. The possible manipulations of this Rubik s Cube form a group. In mathematics, a group is an algebraic structure consisting of a set together with an operation that combines …
95Phase distortion — In signal processing, phase distortion or phase frequency distortion is distortion that occurs when (a) a filter s phase response is not linear over the frequency range of interest, that is, the phase shift introduced by a circuit or device is… …
96Modal bandwidth — Modal Bandwidth, in the discipline of telecommunications, refers to the signalling rate per distance unit. The signalling rate can typically be measured in MHz, and the modal bandwidth is expressed as MHz·km (multiplied). The Modal bandwidth of a …
97Flying ice cube — In molecular dynamics (MD) simulations, the flying ice cube effect is a numerical integration artifact in which the energy of high frequency fundamental modes is drained into low frequency modes, particularly into zero frequency motions such as… …
98Digital down converter — In digital signal processing, a digital down converter (DDC) converts a digitized real signal centered at an intermediate frequency (IF) to a basebanded complex signal centered at zero frequency. In addition to downconversion, DDC’s typically… …
99Multiregional origin of modern humans — A graph detailing the evolution to modern humans using the Multiregional theory of human evolution. The horizontal lines represent multiregional evolution gene flow between regional lineages. In Weidenreich s original graphic (which is more… …
100Geostrophic wind — The geostrophic wind is the theoretical wind that would result from an exact balance between the Coriolis force and the pressure gradient force. This condition is called geostrophic balance. The geostrophic wind is directed parallel to isobars… …
