Is impulse response the same as step response?

They are related as follows: The step response is the integral of the impulse response. The transfer function is the Laplace transform of the impulse response.

How do you find the impulse response of a system from a step response?

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). A less significant concept is that the impulse response is the derivative of the step response.

What is meant by step response?

In electronic engineering and control theory, step response is the time behaviour of the outputs of a general system when its inputs change from zero to one in a very short time. The concept can be extended to the abstract mathematical notion of a dynamical system using an evolution parameter.

Why it is called impulse response?

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.
