Hello SMATH Forum,
I recently came across a set of MathCad sheets, which I am attempting to extract a small sample; rectified waveform and ripple. As I am trying to reconstruct in SMath, early on, I cannot resolve a few definitions; functions "rect1(...)" and "g1hw(...).
I'm hoping someone can help. Attached is my SMath sheet and the reference MathCad15 files.
I welcome your review and look forward to your reply.
Sincerely,
Norm

... added numerical convolution.
From brushing the *.PDF "pulse" has no limit.
Show some you need for concluding a project.

Pulses and Waveforms work in progress.sm
Thanks Jean! I hope the attached works now.
The function g1hw fails. The comment "k - not defined". Hopefully, the attached pdf of my fist page give you an idea. Pulses and Waveforms work in progress - nas.pdf
Best regards,
Norm

Hi Norm. Some few notes:
- For speed up the code, you must to put at some places some eval() in SMath.
- Some vectorization are automatics in Mathcad, but not in SMath. Here you can use the index nk instead implicit or explicit vectorization, as shows the picture.
- N0.gc is 2^8, and it is for use as the finite index for fast Fourier sums, but it's too big for SMath. Use something lower.
- T.hw is undefined in you worksheet.
Best regards.
Alvaro.

Thanks Jean! I hope the attached works now.
Your latest version opens, but SS 6179 complains, can't make it work.
Can you reproduce as doctored by Alvaro, to see something.
Experiment the Pulse Train ... it does a lot !
Cheers ... Jean

Many thanks Alvaro & Jean,
As always, I appreciate your high-level knowledge using this fantastic tool!
Stay safe and take care.
Sincerely,
Norm

Work in progress...
I gave up on the MathCad "Pulses and Waveforms" conversion.
The attached sheet is not complete, just my attempts at the graphs thus-far. I'll need to spend some time working in the diodes conduction range.
Anyway, using the discharge profile looks close, not correct, but has a close resemblance.

This one is above my head.
On the other hand, Smath depends largely upon "plugins"
and they don't behave all same, i.e: Fourier stuff.
In the mean time, you can visit these 4 examples.
Cheers ... Jean.

This one is very useful as you mesh and range from the creation..
Superb to highlight segments.

Thanks Jean! I'll look at this.
