Hi,

How could be made this kind of pulse signal in Mathcad?

Dug up an old file, see attached.

 

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

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.

How about f.periodic ? 😈

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.

Additional information:

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

 

@Cornel 

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.
