How do you find impulse response from input and output?
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.
How to find impulse response of LTI system from input and output?
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 the impulse response can be obtained?
Impulse function is a derivative of step function hence impulse response is obtained by differentiating the step response. The response of the above system is Y(s) = H(s).
How do you calculate unit impulse response?
Calculating the impulse response of a system
To find the unit impulse response of a system we simply take the inverse Laplace Transform of the transfer function.
