- Yes, second draft even if it still says "1st draft".
This half an hour movie comprises the essence of what are in reality four lecture hours. The difference, I think, are the in-class questions and answers. I expect that with a discretionary use of the "pause" and rewind, the viewer can answer most of the possible questions. I also recommend that, before watching this video, you go back to your math courses class notes of Laplace transform and review that until you are fluent in the time to complex frequency conversion process again (as you were when you took those math courses). Good luck, sincerely!
The clearest lecture and explanation I have ever watched with the best illustration. You are a gifted teacher, Professor. Thank God for your gift and you as a teacher.
the best video i have seen for Laplace Circuits
Thank you very much
Thanks rolinychupetin. If I had had a teacher like you who had your teaching skills and humor, I would have learned a lot more in the past.
Wow, thanks!
Wow. After leaving my first lecture today I was filled with absolute dismay. Thanks to your video, I can now say that I have the confidence to propel me through this course. Muchas gracias.
+Alex Schulte You are welcome.
Your explanation and voice is awesome . Best vedio found in this topic.
Brilliant professor, explaining quite difficult stuff in best way possible, in my opinion. Like very many clever people of this world he is also a nice person. I wish nice and clever people had more power and influence.
If I was not so old, I would still be able to blush ... a little. Thank you for your kind words Mr. Hestad.
best explanation on the subject i have found so far! the approach, the explanation, the content, even the voice used and the choice of words. Many many thanks. More power to you
+Rizalenyo Ibarra And thanks to you for posting those very kind words. I truly appreciate it.
you are the best. the way you talk is very soothing I can listen for hours and hours to you
At last, someone who includes the u(t) factor in their equations for causal Laplace examples! But there's a consequence for your linearity slide... u(t)f(t) + u(t)g(t) = F(s) + G(s)
Thank you for your kind comment, Mr. Wibberley.
Sir this is absolutely fantastic! Thank you so much for making this resource.
The only one lecture i got, in which ...I know why in case of inductor in Laplace domain Sl acts as impedance and in case of capacitor 1/Cs act as impedance, and how they are related to ohms law in time domain.
The Best lecture.
Thank You Sir..
Waiting for upcoming of lectures
Thank you Mr. Sapte.
the best video ever
Thank you very much
Another great video, thank you!
best way of teaching
I really like the speed at which you teach
This was great! very good job thank you sir
atractive presentation,i realy like the way he describe laplace
Brilliant lecture! Thanks!
Thank you prof for those wonderfull lessons...i salute you from lebanon-beirut
Thank you! 😃 And thank you for writing and telling me where you are writing from. One of my all time best friends, one of the most important electrical engineers on the planet at this time, is from Lebanon. She has been an inspiration to me. Best wishes.
@@rolinychupetin wow...for you to write this about her then she must be very special , and we are for sure proud of her : )...and be sure prof you are an inspiration for thousands all over the world
Your a good explainer, Thanks .
Fantastic Tutorial, thank you so much!
Glad it was helpful!
One of the best explanations!
Glad you think so!
The best explanation sir
Many thanks from Norway!
You are welcome and thank you for including your location. Greetings from Canada.
Thank you very much sir!!!!!!
Excellent ❤️❤️
clear concept . thanx .
perfect sir... this vedio helped me alot
I'm glad to hear that, I really am. :) Thanks for the feedback.
I am glad and more satisfied as i watched to the end. However, limit as "s" tending to infinity has always kept me thinking. How can a person fix the value of infinity and proceed!!? There is always a bigger number than one can think!! Its like a looped video of a dog chasing its tail.
I agree. The Greek philosophers started that thinking process a while ago imagining a turtle that moves towards a carrot (or was it some lettuce leaf?). Every time it moves, the turtle advances only half of the distance remaining between it and the carrot. It is clear that the turtle will never get to the carrot, but as time goes by, it will get increasingly closer to it. There is no point near the carrot that will not be crossed eventually by the turtle in its relentless journey toward the carrot, but never quite getting to it. The carrot is the actual limit of the journey A limit that is never reached. I don't remember if it was a turtle or a rabbit, it was thousands of years ago ... I have forgotten some details, heh!
@@rolinychupetin Philosophers have wide imaginative thoughts indeed!! Maybe it is because we assume too much, that we end up fixing things, here in this case "infinity"! Come as close to any straight wall and look at either sides just to realize how wide and far the wall is!! Then step further back, Oh!! its just a small wall! The point of view matters, whether to observer the wall up close, further away or inside the wall itself!! To have the slightest glimpse as to where the farthest point is and term it "infinity", but is that really is? Fascinating indeed!
The word that best describes this video is "Profesional".
amazing!!
Brilliant, thanks a lot!
Glad it helped!
So easy to follow
Probably this video cause to get high point for my final exam. soo thanks..
+betül k I'm glad to hear that. Good luck in your final exam.
Well done
Thank you
The best ever!!!
You are too kind. Thanks!
Your voice is magical
That voice puts to sleep my grandchildren every night we coincide with each other, at their dad's (my son). They ask me, "grandpa, can you tell us a story to go to bed?". I make up stories for them, on the go. The youngest one, at seven, rewarded me, in front of parents and friends with "Grandpa's stories are the best!".
Great lecture
Many thanks
hello sir, thank you very much for the video first of all, brilliant. There is one point hat i got really confused, how come did you find the second circuit that you drew ? how can you take sum of all the impedances, aren't them connected in parallel ? what happened to the voltage source ? thank you very much
The circuit that you seem to be referring to is the circuit after t = 0. In that circuit, the switch has opened already so the source is not part of the circuit anymore. When the switch was in place, in the time domain, the two resistors that you are talking about were indeed in parallel, but once the switch opens, they are not in parallel anymore. this is a new circuit with a new topology, they both are in the same and only branch ... they are in series now. I invite you to watch another video in this channel, this one: czcams.com/video/97ZyjCFXlFk/video.html
Nice vid.... :)
Great tutorial!!! Intro music by???
Thanks! The music is part of a copyright free package that came with my video editor, it is called Calypso Breeze, but they don't provide the name of the composer or of the performers. I like this relaxed intro, it sets the mood for the style and rhythm of the video/lecture.
rolinychupetin Thank you very much! Your approach is very interesting. Subscription added...
The mainstream media: ´Gabby Giffords is back´.
Me: watches a video about Laplace Transforms...´Laplace transforms are back´.
Heh! *Remote and CV19 safe high five to you!"
So, the application of Laplace transform in circuit analysis is to solve first-order and second-order *DC* circuits, right?
Not in DC. in cases where the signal contains an indefinite number of frequencies, but not only first and second order. Any order. And much more than that, as future sessions will show: analysis of stability of electric systems, in control theory and more.In DC-SS, we just work as in the series in Electric/Electronic playlist in this channel, which is simpler as all equations are algebraic.
@@rolinychupetin Oh, I see 🤔 This math is art. Thank you for the explanation!
it is the easiest thumbs up
tasteful.
