Time-invariant system — A time invariant system is one whose output does not depend explicitly on time.:If the input signal x produces an output y then any time shifted input, t mapsto x(t + delta), results in a time shifted output t mapsto y(t + delta).Formal: If S is… … Wikipedia

Time-variant system — A time variant system is a system, that is not time invariant(TIV). Overview There are many well developed techniques for dealing with the response of linear time invariant systems, such as Laplace and Fourier transforms. However, these… … Wikipedia
Shift invariant system — is the discrete equivalent of the time invariant system; defined such that if y(n) is the response of the system to x(n), then y(n k) is the response of the system to x(n k) [ Oppenheim, Schafer, 12 ] . ApplicationsBecause digital systems need… … Wikipedia
System identification — In control engineering, the field of system identification uses statistical methods to build mathematical models of dynamical systems from measured data. System identification also includes the optimal design of experiments for efficiently… … Wikipedia
System analysis — See also systems analysis. : MISO redirects here, for the data line see Serial Peripheral Interface Bus. System analysis is the branch of electrical engineering that characterizes electrical systems and their properties. Although many of the… … Wikipedia
Time dilation — This article is about a concept in physics. For the concept in sociology, see time displacement. In the theory of relativity, time dilation is an observed difference of elapsed time between two events as measured by observers either moving… … 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
LTI system theory — or linear time invariant system theory is a theory in the field of electrical engineering, specifically in circuits, signal processing, and control theory, that investigates the response of a linear, time invariant system to an arbitrary input… … Wikipedia
Distributed parameter system — A distributed parameter system (as opposed to a lumped parameter system) is a system whose state space is infinite dimensional. Such systems are therefore also known as infinite dimensional systems. Typical examples are systems described by… … Wikipedia
Autonomous system (mathematics) — In mathematics, an autonomous system or autonomous differential equation is a system of ordinary differential equations which does not depend on the independent variable. Many laws in physics, where the independent variable is usually assumed to… … Wikipedia
