How to approximate Diracs delta function?

I need to make voltage source controlled with Dirac’s function.

To make either triangle or rectangle impuls which area is equal to 1.

Can you please help me?

Attached is an example of how to construct Dirac approximations for square and triangular approximation types. The example includes how to construct a single event or a periodic event. The approach uses simple geometry to ensure that an impulse of the specified width has a total area of 1. The integration of the Dirac approximations is 1, as expected.

Note that a few parameters are specified in the Model Initialization Commands.
