Why convolution is used in LTI system?
Therefore, in signals and systems, the convolution is very important because it relates the input signal and the impulse response of the system to produce the output signal from the system. In other words, the convolution is used to express the input and output relationship of an LTI system.
What is convolution in a LTI system?
Convolution Integral
The output of any LTI system can be calculated using the input and the impulse function for that system. Convolution has many important properties: Commutativity: x ( t ) ∗ h ( t ) = h ( t ) ∗ x ( t ) x(t) \ast h(t) = h(t) \ast x(t) x(t)∗h(t)=h(t)∗x(t)
Which is the commutative property of the LTI system?
The commutative property means simply that x convolved with h is identical with h convolved with x. The consequence of this property for LTI systems is that for a system with a specified input and impulse response, the output will be the same if the roles of the input and impulse response are interchanged.
What is the purpose of convolution in signal processing?
Convolution is important because it relates the three signals of interest: the input signal, the output signal, and the impulse response.
