What is the impulse response of a linear time invariant system?
The impulse response for an LTI system is the output, y ( t ) y(t) y(t), when the input is the unit impulse signal, σ ( t ) \sigma(t) σ(t). In other words, when x ( t ) = σ ( t ) , h ( t ) = y ( t ) .
What is meant by the frequency response of an LTI system?
=frequency response function. The response of an LTI system to a sinusoidal or complex exponential input is a sinusoid or complex exponential output at the same frequency as the input. LTI systems cannot change frequencies.
What three properties must a linear time-invariant LTI system have?
The three basic properties of convolution as an algebraic operation are that it is commutative, associative, and distributive over addition. The commutative property means simply that x convolved with h is identical with h convolved with x.
What is linear time-invariant and linear time variant system?
In system analysis, among other fields of study, a linear time-invariant (LTI) system is a system that produces an output signal from any input signal subject to the constraints of linearity and time-invariance; these terms are briefly defined below.
