time-invariant
Adjective
Meaning
time-invariant (comparative more time-invariant, superlative most time-invariant)
That does not vary over time.
Examples
A simple feedback control loop If we assume the controller C, the plant P, and the sensor F are linear and time-invariant (i.
Impulse response and transfer function A linear time-invariant (LTI) filter can be uniquely specified by its impulse response h, and the output of any filter is mathematically expressed as the convolution of the input with that impulse response.
In engineering applications, a function corresponding to a linear time-invariant (LTI) system is stable if every bounded input produces a bounded output.
Mathematics of filter design collapsible LTI system theory describes linear time-invariant (LTI) filters of all types.
The term is often used exclusively to refer to linear, time-invariant systems (LTI), as covered in this article.
Idealized system model This section describes a simple idealized OFDM system model suitable for a time-invariant AWGN channel.
