## How to construct in Mathcad this kind of pulse signal with these characteristics?

Dug up an old file, see attached.

You could try out what remains of it when you translate to Prime.

Success!

And I want to be able to select how many pulses to be displayed if possible:

Here you are, but please don't ask for the Fourier transform of those signals! 😉

RL circuit. R=1 kohm, L=3 H.

It returns infinity index error. Assume using 8 ms data of f.periodic, we can get digital data and convolution can solve it.

We've been through similar stuff before, see https://community.ptc.com/t5/Mathcad/Creation-of-Triangle-Waveform-and-Circuit-Analysis-with-Laplace/m-p/713269

And especially this one, you started yourself: https://community.ptc.com/t5/Mathcad/Square-Sine-and-PiceWise-Linear-Waves-Functions/m-p/718121#M194834

That was exactly the reason why I requested Cornel NOT to ask for the Laplace transform in a follow up question (I was pretty sure he would do so) 🙂
After all he was just asking for the construction of the signal, nothing more.

I did not remember the second thread you linked to where I already had posted a (somewhat nicer) suggestion for the very same signal - annoying.

I found this to be a handy reference.

Here is some more material on creating waveforms in Mathcad.

Marcello @-MFra-  also kindly provided the Mathcad files for his Waveform Spectra here: Fourier Analysis and Signals' Spectra
I may be wrong but as far as I remember he never shared the Mathcad file for his Test Signals. He only posted the static pdf here: Test Signals 1.pdf

Marcello also contributed to your Electrical Engineering Challenge #2

But his two very large postings consisted of hard to read pictures only and were missing the Mathcad files, so you may have overlooked or ignored them.

The material I have is in Mathcad 15 type files. They don't convert very well. So I bothered not to post them.

Luc, I see something in the PULSE signal: in description is said that if n=0 then should I see pulses on the entire range definition of time t (something like orange), right?
Can have a look?

It's a wish that didn't come true...yet.

Success!

Ah, ok, understood. But I think its ok even this thing with unlimited pules for n=0 did not come true yet. We can put n a bigger number to have full pulses on the entire range of time t, and should be fine.

@LucMeekes I see also that there are two definition for puls_(). There is a difference somewhere between the two? At first view I do not see

I think I see, one of them is not good, right?
puls1_() seems to be the one which is good.
