What is the meaning of impulse response?

Definition English: In signal processing, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse. More generally, an impulse response refers to the reaction of any dynamic system in response to some external change.

What is impulse and step response?

Definition: The impulse response of a system is the output of the system when the input is an impulse, δ(t), and all initial conditions are zero. Definition: The step response of a system is the output of the system when the input is a step, H(t), and all initial conditions are zero.

What is impulse response of the system *?

Key Concept: The impulse response of a system is given by the transfer function. If the transfer function of a system is given by H(s), then the impulse response of a system is given by h(t) where h(t) is the inverse Laplace Transform of H(s).

Why do we impulse response?

Why the impulse response is important. The impulse response of a system is important because the response of a system to any arbitrary input can calculated from the system impulse response using a convolution integral.
