thank you

Hey there , all well? Long time and no video of yours came so just a follow-up comment 😊

So much positivity for a clusterfuck of demonstration. I spent more time being grossed out by your elbows

One of the biggest mystrey is solved today😅

Parabens

Great explanation, tranks!

Finally a clear cut answer, thank you.

Hey man, I just want to say I graduated my engineering because of your videos , I hope you will get good things in life <3 I graduated in 2016 and its been a lot of years now but It felt great seeing you posting again , keep up the good work buddy!!

cool cheers

You dont know me but this video made me pass my dc engineering exam

the power of what components ? the same that the voltage ?

Your hand move too many unnecessary.

God bless you! <3

Life saviour , keep it up good work :)

Robert this is excellent explanation.

camera position is very bad. please fix the camera position.

thank you so much for this video! I've been trying to understand this concept for days for a project and you made it so easy! It really is a joy to watch your videos

Thanks for the video. I came here because I heard that "Modulations techniuqes like QAM and QPSK are used for optical signals". I'm looking to understand how light is used to convey data through fibre optic lines for the internet.

Thank you so muck Sir! You've helped me understood this topic.

What,about current

Thanks

Great helppp :))) thank youuu

Wow...Robert. That's super way of explaining. Was dumb about 'QAM'...but no more...Kudos to you.

Great Video Robert, I spent 10 years as a fixed wireless access engineer working up to 256 QAM for PtMP radio systems for Cellular back haul. I always had an understanding of this, but your video has made it much clearer.

Wow! I need that. At the school don't pay enough attention to this and now i need it. Thank you very much. And congratulations for the video!.

this is such simple way of understanding thank u sir

based on what I understood from the video, the second point on the waveform deriving to binary 11 should be at -1 (not 0). at 17:48 of the video.

Thankyou very much agreat job

Why 10 log not only log

Awesome Explanation Robert.... I believe you are the outstanding Professor..Thank a lot and keep posting more video..

Awesome Explanation Robert.... I believe you are the outstanding Professor..Thank a lot and keep posting more video..

Great piece of work Robert, thanks so much. Do you have any complementary video explaining how X.QAM (X>4) waveforms are built? I mean constellation points with no constant amplitude unlike QPSK has. Thanks!

what is 16QAM 2/3 or 16QAM 3/4? help me <3

are you related to Mr Weber the famous Physicist that has his name of the magnetic flux unit? those 3rd harmonics are here because of the clipping of the amplifier characteristics and shaping the sine wave to look like a square wave which only contains odd harmonics...you made it sounds like the 3rd harmonics are the reason for the clipping which is rather wrong...don't you agree?...we are concerned about the 3rd one because it is just after the fundamental frequency in odd sequence 1,3,5,7,.... the 5th and up will be weaker powers and can be ignored. i don't know Rob... you have a nice track but a bit vague.

Precise and simple! Thanks!

thankyou ! This thing was headache , now solved.

34 minutes to explain binary numbers? 4 fuck sake!

My lecturer told me 16-QAM has 3 amplitude as against 2 amplitude as you've stated. What do you have to say to this???

Really good. thank you. I had same question when I am going though amplifier spec. Thanks for explanation

Awesome sir....

But I’m 15!! Nooooooooooooooooo

Very well explained, thaks

You are awesome Robert! I just come here to find how to calculate TOI point and didn't get anything except a lot of good information, thank you teacher.

Do you have a plane to catch? Why are you talking so fast? Some of us are enthusiasts or hobbyists who want to learn - if we were professionals in the field, why would we watch this video? Please slow down, or don't even bother, mate.

Good!

Can this also be done for hf? Lower freqs than 2.5g

How does propigation affect it?

So is the antenna creating the bean and the rotating vorticy of the beam? Or isit done to multiplexing at the transmitter or at the amplifier or is this all done as a result of digital encoding and decoding I'm really just finding out about this today and trying to understand it
