Thank you for that. Many ageing amateur radio enthusiasts like myself will likely be grateful for your very straightforward introduction to this black art.
I wish some one could force my lecturer to watch this video and learn how you teach an undergraduate student. Sometimes they seem to be teaching PhD students. Seriously... So frustrating. Thanks for the video. Saved me 3 hours of lecture with her/him. :D
Nice video. But how did you obtain the initial 50 +j50 load impedance values. Do you measure those with a scope in some way? I.e the resistance and reactive components of the load? I really would like to know exactly how you get those values from the physical load. Help!!
Good overview on how it works. But I still have a question. You said it tells "How well matched your load impedance is to the rest of the line - you could use the Smith chart." So now that we plotted those values - what do they tell us about that impedance matching? Thanks.
I've been in RF since 1993. The longer I work in this field the less it feels like black magic, but also the longer I work in the field, the more I'm convinced its black magic. It all depends on what you truly understand.
@@eriknunezalbermann9993 It seems like in every interview I’ve had I was asked the formula for cascaded noise figure. 😊Of course research the company’s products as much as possible. What gets people hired is them being enthusiastic and passionate. I train people a lot. It takes about a year until they are independent. So they don’t expect you to get everything right. Brush up on the fundamentals. How do you add dBm + dBm? That was another question. Good luck!
I can plot all this no problem, but what do I do with it next? Is the goal to bring the impedance closer to the purely Resistive axis from a design standpoint? If I'm way out on the edge is the goal to design a network system that counteracts the impedance mismatch with hardware to say add more capacitance or inductance if your on one side or the other? sorry just a dumb mechanical engineer here who's just curious how to apply this. recently started working in RF and want to understand more.
You showed how to plot the complex impedance but didn;t answer the original problem: how well matched is the load to the characteristic impedance, is that expressed in dB? %? how much match is enough?
Hi sir, i have a question. I hope you can answer. This is the statement: you have a transmission line, when you have put your stub afar from load, you have a characteristic load and after the stub, you have a different charateristic load. How can i make the coupling?. Please, answer as soon you can.
When somebody explains logarithmic scales, I wouldn't say that he missed the function of voltage dividers. It shows correctly how and impedance is calculated and how Z is found in a Smith chart.
+Kashmin Patel I've done that before but the quality of print, at least form my printer, is poor and in B&W. I'd much prefer pre-printed like I see our presenter here using and as I see other folks using.
Thank you for that. Many ageing amateur radio enthusiasts like myself will likely be grateful for your very straightforward introduction to this black art.
Thank you for this video. You made someone's life easier. God bless!
this short video was better and easier to understand than my hour lecture + text book. it helped me finish my homework. thank you!
step by step tutorial, every thing is stable....so your info directly to my brain thank you
make a 1080p
Dude, respect. No matter how sofisticated Asians or European want to make it look, there´s no substitute for plain old American simplicity.
At first i thought you were very naive with pencil and paper, but this is actually pretty good!! Thank you very much! :)
thx a lot, you're explanation is so smooth and great, as they say : It takes a lot of work to make things look easy

you're great.... we need more good teachers in America
Very well.You are my teacher now..
Many thanks. Clear, concise, and exactly what the title said it would be.
Better than what my teacher taught
you just made my life much easier, cheers dude you a legend
Thank You Mr Simple and straight forward.
That's a must watch video! Wonderful job.
Nice video. But how did you obtain the initial 50 +j50 load impedance values. Do you measure those with a scope in some way? I.e the resistance and reactive components of the load? I really would like to know exactly how you get those values from the physical load. Help!!
You, sir, are a lifesaver.
Carl, that was easy for me to follow! Thanks and keep up the good work!
Thank you. You achieved to explain easily, what my teacher could not explain...
Good overview on how it works. But I still have a question. You said it tells "How well matched your load impedance is to the rest of the line - you could use the Smith chart." So now that we plotted those values - what do they tell us about that impedance matching?
Thanks.
As long as the plotted point is near the prime center, means that is a good impedance matching .

Any tips to get an RF job? -Electrical engineer grad with antenna classes(:

it helps a lot!! online learning is so hard and i have a test tommorow lucky me, i found this video
Thank u so much Carl Oliver, it helped a lot!
I dont know how to say thank you for your good work..........*1000000000thank you very much
Brilliant.I dont know who you are but I must call you sir now
love how u call me an expert fast :D thanks for the tut
if you have a negative value on the the imaginary part of load impedance, the line matching the points should be downwards ?
Thanks! Explained simply and clearly!
Thankyou soo much.. i have an exam tomorrow and this helped me a great deal..
Make video on stub matching
Great video very easy to understand
god bless you you saved my semester and my finals thnx so much
A 300 ohm transmission line is terminated with an antenna that presents a (450 ohm - j600 ohm) load impedance. What is the normalized load admittance?
240P only?
No, you also have the option of 144P
I can plot all this no problem, but what do I do with it next? Is the goal to bring the impedance closer to the purely Resistive axis from a design standpoint?

thank you sir you saved my life
Enjoyed from Brazil.

Hey Carl , i am a little late to your channel :-) but what determines if its a - or + ? am i looking to hard ? cheers mate ! great tutorial 🙏
brilliantly explained
Thanks Carl and TH-cam, nice bro
Excellent! Thanks a bunch.
thank you sir! this is really gonna helpful for me

WOW, Excellent video!
wow!! its a great tutorial. you are a savior :)
thanks alot. all 3 part was excellent nd so much helpful .
You are welcome!
Thanks you have saved me in my EMFT paper:)
you are god my friend, helped me a lot
god. really for showing a smith chart?
good*
Excellent, thank you!
I want to meet Mr Smith ! That dude was genius!
excellent video mate
Great video,
Much appreciated
Quick and easy!! Thanks!
The basics of a smith chart should include two things that were left out in this video. Inductance and Capacitance.
When somebody explains logarithmic scales, I wouldn't say that he missed the function of voltage dividers.
It shows correctly how and impedance is calculated and how Z is found in a Smith chart.
can you upload video about stub and double stub matching?
Really appreciate it, thanks. It makes it easy to be understand XD
Thank you sir very nice Explaination
thanks a lot, cannot be clearer than this.
Thank you so much sir for sharing this knowledge...
What if the Normalized R is negative?
thanks, This Video helped me to understand the basics of Smith Chart :)
Thank you, Carl!!!
Well explain sir..Thank you so much 👌
Concise and precise, thanks!
thankyou, sangat membantu saya
Excelent Video. Congratulations !
cannot plot -j0.5 on my chart, the semi-circle for the imaginary stops when it crosses R = 2
what is sending end impedence
awesome explanation
thank you sir
thank you all the way from egypt
thank you you saved my final
+DREAMWORKERSKY He saved my final too :'D
una explicación rápida y sencilla, gracias :)
Can someone tell me where I can purchase smith chart graphing paper?
+Mike Dannhardt just download online from somewhere, print them...
+Kashmin Patel I've done that before but the quality of print, at least form my printer, is poor and in B&W. I'd much prefer pre-printed like I see our presenter here using and as I see other folks using.
thank u thank u so much ...!!!!!!!
plz also update the videos of electrical network als0
Thanks..
you saved me!
Great video thanks!
Thank you 😭😭😭😭
awsome video. thx bro!!!
continue like this .
GOD bless you sir. Really. I mean it
thnk you sir....It was very helpful....
you saved me.. thanks
thnx man..really helpful..
Thank you. Sir
Samuel Liao! You managed to complicate such simple shit!Thanks for the video
Thank you so much bruhh!!!
Man, I understand now!!!
Thank you sir.
Helpful. Though when one needs a calculator to divide 300 by 50, or 25 by 50...
but what if the real part is negative ?
It means hole in a head. Electricity is not yours.
In all the tests I've taken, Extra Class Amateur and commercial.
There was never a question about Smith charts.
Just keep going as if there were still a line there. In the video I go past R' = 2 at 7:16.
OSM!! Tutorial sir...
realy helpful video.
Helpful sir..Thank you:D
thanks for this video
excellent!Thanks a lot!
