What is impulse response in simple words?

Impulse response represents the effects of unit shocks in the variable of a system after some periods. Impulse response functions (IRFs) are used to evaluate the effectiveness of a policy change. An impulse response refers to the reaction of any dynamic system in response to some external change.

What is impulse response equation?

The impulse response of a discrete-time system is defined as the response of a discrete-time system when the input is a delta pulse, thus x[n]=δ[n] x [ n ] = δ [ n ] .

What is impulse response model?

An impulse response model of the process is used to predict the output for a certain period of time. In this paper special attention is given to the algorithm to deter- mine input sequences, minimizing the differen- ces between predicted and desired trajectories over this period.

What is the purpose of 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.
