What is impulse response of LTI 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 ) .
How do you calculate response of LTI system?
A linear time-invariant (LTI) system can be represented by its impulse response (Figure 10.6). More specifically, if X(t) is the input signal to the system, the output, Y(t), can be written as Y(t)=∫∞−∞h(α)X(t−α)dα=∫∞−∞X(α)h(t−α)dα.
How do you calculate impulse response?
Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into the system. If the system is linear and time-invariant (terms we'll define later), then you can use the impulse response to find the output for any input, using a method called convolution that we'll learn in two weeks.
What is impulse response of LTI recursive system?
To derive the response of an LTI system G to an arbitrary input, we begin by defining the system's impulse response h[n] as the output sequence given a unit impulse input sequence: h[n] := Gδ[n]. = ··· + u[−1]δ[n + 1] + u[0]δ[n] + u[1]δ[n − 1] + ... for all n.
