• 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

• 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 reversibility — is an attribute of some stochastic processes and some deterministic processes.If a stochastic process is time reversible, then it is not possible to determine, given the states at a number of points in time after running the stochastic process,… …   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

• Analog signal processing — is any signal processing conducted on analog signals by analog means. Analog indicates something that is mathematically represented as a set of continuous values. This differs from digital which uses a series of discrete quantities to represent… …   Wikipedia

• Digital signal processing — (DSP) is concerned with the representation of discrete time signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. DSP includes… …   Wikipedia

• Analytic signal — Not to be confused with Analytic function. In mathematics and signal processing, the analytic representation of a real valued function or signal facilitates many mathematical manipulations of the signal. The basic idea is that the negative… …   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
