Causal system

Index Causal system

In control theory, a causal system (also known as a physical or nonanticipative system) is a system where the output depends on past and current inputs but not future inputs—i.e., the output y(t_) depends on only the input x(t) for values of t \le t_. [1]

Anticausal system

An anticausal system is a hypothetical system with outputs and internal states that depend solely on future input values.

Causal filter

In signal processing, a causal filter is a linear and time-invariant causal system.

Causality

Causality (also referred to as causation, or cause and effect) is what connects one process (the cause) with another process or state (the effect), where the first is partly responsible for the second, and the second is partly dependent on the first.

Causality (physics)

Causality is the relationship between causes and effects.

Control theory

Control theory in control systems engineering deals with the control of continuously operating dynamical systems in engineered processes and machines.

Digital signal processing

Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations.

General relativity

General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.

Impulse response

In signal processing, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse.

Linear time-invariant theory

Linear time-invariant theory, commonly known as LTI system theory, comes from applied mathematics and has direct applications in NMR spectroscopy, seismology, circuits, signal processing, control theory, and other technical areas.

Nature

Nature, in the broadest sense, is the natural, physical, or material world or universe.

Physical system

In physics, a physical system is a portion of the physical universe chosen for analysis.

Special relativity

In physics, special relativity (SR, also known as the special theory of relativity or STR) is the generally accepted and experimentally well-confirmed physical theory regarding the relationship between space and time.

System

A system is a regularly interacting or interdependent group of items forming an integrated whole.
