time-invariant filter

См. также в других словарях:

  • Filter design — is the process of designing a filter (in the sense in which the term is used in signal processing, statistics, and applied mathematics), often a linear shift invariant filter, which satisfies a set of requirements, some of which are contradictory …   Wikipedia

  • Time constant — In physics and engineering, the time constant usually denoted by the Greek letter au , (tau), characterizes the frequency response of a first order, linear time invariant (LTI) system. Examples include electrical RC circuits and RL circuits. It… …   Wikipedia

  • Time Delay Neural Network — Schema eines TDNNs, mit dargestellten Aktivierungen. Ein Time Delay Neural Network (TDNN, zu deutsch etwa Zeitverzögertes Neuronales Netz) ist ein mehrschichtiges künstliches neuronales Netz, das durch die Verwendung von Zeitfenstern über mehrere …   Deutsch Wikipedia

  • Kalman filter — Roles of the variables in the Kalman filter. (Larger image here) In statistics, the Kalman filter is a mathematical method named after Rudolf E. Kálmán. Its purpose is to use measurements observed over time, containing noise (random variations)… …   Wikipedia

  • Digital filter — A general finite impulse response filter with n stages, each with an independent delay, di, and amplification gain, ai. In electronics, computer science and mathematics, a digital filter is a system that performs mathematical operations on a… …   Wikipedia

  • Linear filter — A linear filter applies a linear operator to a time varying input signal. Linear filters are very common in electronics and digital signal processing (see the article on electronic filters), but they can also be found in mechanical engineering… …   Wikipedia

  • Electronic filter — Electronic filters are electronic circuits which perform signal processing functions, specifically intended to remove unwanted signal components and/or enhance wanted ones. Electronic filters can be:*passive or active *analog or digital *discrete …   Wikipedia

  • Causal filter — In signal processing, a causal filter is a linear and time invariant causal system. The word causal indicates that the filter output depends only on past and present inputs. A filter whose output also depends on future inputs is acausal. A filter …   Wikipedia
