What are the properties of impulse function?

The unit impulse function has zero width, infinite height and an integral (area) of one. We plot it as an arrow with the height of the arrow showing the area of the impulse. To show a scaled input on a graph, its area is shown on the vertical axis.

Is the discrete time unit impulse response?

In discrete time the unit impulse is simply a sequence that is zero ex- cept at n = 0, where it is unity. In continuous time, it is somewhat badly be- haved mathematically, being of infinite height and zero width but having a finite area. The unit step and unit impulse are closely related.

How do you find the unit impulse function?

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.

Is impulse function discrete?

The discrete time unit impulse function, also known as the unit sample function, is of great importance to the study of signals and systems. The function takes a value of one at time n=0 and a value of zero elsewhere. It has several important properties that will appear again when studying systems.
