HP16/Laplace/Circuits: Laplace and Plotting with the HP50g.

A tutorial on using the HP-50g to solve an electric circuit with inductors and capacitors in the Laplace domain. If you don't care about electric circuits but only about the HP50 and plotting and Laplace, just skip the video up to the point where the two equations in the Laplace domain are ready for us to find the inverse Laplace transform, and then plot the time domain representations.

A hero. Not the hero we deserved but the hero we needed.

Thanks to all of you, for your kind words. I sincerely hope that it helps on the way to your becoming a better engineer.

[@mugzzzified]

Thank you so much Dr. Linares. These tutorials really relieve all the pressure we face right before a midterm.

I used the KVL to list the system equation to get the I(s) expression, and found the importance of separating the "voltage part" and "impedance part" in equivalent models of capacitors and inductors, as I need to find the voltage polarities of all components. Thank you so much Sir.

[@rolinychupetin]

Glad to be of help.

[@melmore123]

Thank you for uploading this! This is the best explanation I have found for using the Inverse Laplace function of my HP calculator. As a Mechanical Engineering student, I also found your analysis of the RLC circuit very helpful in relation to a Controls class that I am currently taking.

[@Chrls5]

Man, this is just the best!!! i love your tutorials!!! For real,, they are so freaking useful to me!,, you are the best!!

[@RandyLott]

Wow. You are incredible. It's so interesting! Thank you, I'm so grateful for your efforts.

You identify at timestamp 9 minutes and 11 seconds, a problem when displaying equations that cannot be entirely viewed on the 50G screen.
There is a fairly undocumented method to view equations longer than the screen size that allows the user to scroll the 50g screen left to right.
just UPARROW in the stack to the unviewable equation, then press softkey VIEW (should be F2).
Now use LEFT or RIGHT ARROW to scroll screen.
Please keep posting more great engineering videos using the 50G !

It is important that you set up your calculator correctly!
In video HP01, the author sets flag 105; thereby setting CAS to Approx mode.
In this example, flag 105 is not set; therefore CAS is in Exact mode.
You can see this setting at the top of the stack, in the display header:
RAD XYZ HEX R =
The "=" denotes CAS Approx mode.
In video HP01, the CAS is in Approx mode ("~"):
RAD XYZ HEX R ~

Thanks for the upload. Greatly appreciate it!

[@undergroundcity123]

I really appreciate this video, Thank You so much !!

[@rolinychupetin]

There is no "inverse Laplace button". As seen in previous videos of the series, I have assigned the internal function ILAP, which includes some system flags setting (as per the Advanced User Manual that comes in a CD with the machine), to one of the soft keys at the top of the keyboard.

[@safire920]

thanks for the great tutorial!

[@rolinychupetin]

Assign this little program to any F key: -105 SF -3 CF -17 SF ILAP (enclosed in the usual chevrons, that RUclips won't let me type here), call it ILAPL (to avoid the reserved name ILAP). Good luck. Refer to the video on "variables and the HP50g".

[@rolinychupetin]

Also ... I'm using version 2.15 of the ROM. The one I advised everybody to upgrade their machines to during the semester.

[@kwijibo12]

Hi there, I cannot seem to find the inverse laplace button on the hp50g

[@kwijibo12]

Thanks!

[@execrable3000]

This works on hp49g+ ???

[@rolinychupetin]

I have not used the HP49g+ in more than ten years. Honestly, I don't remember but I Googled it and got that the functions on the 49g+ are LAP and ILAP. Check this out www.manualslib.com/manual/359363/Hp-49gPlus.html?page=485#manual.

@channelloo 我很樂意幫忙

[@rolinychupetin]

Go to ece dot ubc dot ca slash tilde eece251. On the left, you'll see the main menu of the site. Click on "FREE SOFTWARE". (RUclips won't let me post links as a post).

[@merzouguihoussine3997]

did the same with the prime :)

[@rolinychupetin]

In the HP Prime it is so much easier. Mostly because the software is more modern and powerful. The HP Prime uses the excellent XCAS/GIAC, which open software and has tons of Brainiacs led by Bernard Parise improving it continuously (a bit like a Tesla car, you get updates for the Prime twice a year ... for free.)

[@NickApostolakis]

I find prime a lot easier to use as well. That does not mean 50g is not valuable or powerful, it’s just prime is a better.
