What is impulse response, why it is important? How else is it called?

Expert Solution

Impulse Response:

Whenever a system (block) or a signal processor is given an input signal, it alters or processes the input to give the desired output signal depending on the system transfer function.
The output of the system to a unit input signal is the impulse response of the system.
Impulse response of the system helps in determining the main characteristics and response of the system (block) for any kind of input signal.

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.

Convolution is a very powerful technique that can be used to calculate the zero state response (i.e., the response to an input when the system has zero initial conditions) of a system to an arbitrary input by using the impulse response of a system. It uses the power of linearity and superposition.

1. a) Compute the impulse response of the following filters. If the impulse response is infinite, feel free to stop once a pattern becomes apparent. i. y[n] = 2/3 · x[n − 1] − 1/3 x[n − 2] ii. y[n] = x[n − 1] − x[n − 2] − 1/3 y[n − 2] b) What are the feed-back (b[k]) and feed-forward (a[k]) coefficients of the following filters? You may assume that a starts at delay of k = 1 (i.e.,...

Percent Overshoot Problem for a Unit Impulse Response

The unit impulse of a system (which isn't necessarily 2nd order) is shown in the figure. In the figure, A denotes the shaded area. You must show that the percentovershoot of the output in response to a step input (%OS) is a linear function of the shaded area A. Show also that the %OS is dependent only on A and the transferfunction DC gain.

Is it only a primate's rank that predicts its stress response? If not, what else is important? Why is studying dominance hierarchies and stress more complex in humans than in baboons? What makes living in poverty so stressful? Explain the role that Sapolsky believes that health care access, risk factors, and feeling poor, play in accounting for the average worse health that people living in poverty experience.

What does impulse do to an object? How does a large impulse affect an object differently Than a small one? Use what you said above to answer: What does the presence of an airbag do to a person's head during an automobile collision? Answer in terms of impulse, impact, force, and time using complete sentences. So finally in terms of impulse and momentum, why do airbags make automobiles safer?
