How do you calculate the output of an LTI system?
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)
How do you find the output given the input and transfer function?
To find the output, we multiply the transfer function by the input, and solve. We can find the inverse Laplace Transform by performing a partial fraction expansion to get the solution into forms that are in the table.
How do you find the transfer function from output?
A transfer function H(f) of a system with input (reference) x and output (response) y is written as the ratio H(f)=Y(f)/X(f), where X(f) is the Fourier transform of x and Y(f) is the Fourier transform of y.
When the input to an LTI system is?
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.
