@@csp405 What more can you expect from a 7:25 minute video? This gives a broad and brief idea on Analog & Digital Modulation. I found this useful. Thank you Lesics for your work❤️
I am from electronics branch. I share your videos in our group, we got lot of knowledge from you. Thank you and love you from our college. Please also make videos on Microcontrollers like Arduino, raspberry and etc........ Love you
After searching through many videos on UA-cam about QAM topic, this video is the best in explaining a complex topic in a very simple and understandable way. Thanks.
I'm just get started with the SDR and things around. your resources are really helpful for my research. Anyway I just wanted to thank you and suggest you guys to keep up the great work! Thank you so much once again.
I just need to say that I was watching this channel before they started using click bait. Now I’m watching it despite the click bait. It’s still a very informative channel.
0:54 Slight note: that's not really why we use modulation. While soundwaves, in the KHz, are too slow to transmit with a reasonable antenna, consider that in cases like TV / WiFi the bandwidth would lead to an acceptable frequency in the MHz anyway, so a small antenna would work just fine for those purposes. Yet, we still modulate. So the explanation given only explains radio, not TV or WiFi. The primary reason we need modulation is because it allows _multiple_ streams of information going over the same medium. Many radio stations, Many TV shows, Many devices connected to the WiFi router, etc, all communicating over the same shared air and of course interfering and mixing with each-other. The idea of modulation, is that despite every WiFi device + TV show + Radio Station using the same air to transmit their waves, you can still "tune" into a specific frequency by filtering the overall received electromagnetic signal _by_ a sine wave of the actual frequency you're trying to "tune" into. (Note that, WiFi, in the GHz, can't get through walls or go long-distance easily. So, each WiFi router can use the same frequencies as long as they're in different homes. When multiple WiFi routers share a space, they still ensure a particular frequency isn't being used before trying to use it. Radio waves, over hundreds of miles, act the same if you've ever gone cross-country driving.)
This video has been very helpful in visualizing modulation techniques and it's advantages I really don't know how how parents and grandparents used to grasp these concepts without such visual aids. They have to be the OGs though ngl
Your videos are very helpful for us.,,, PLz make video about Electrical engineering (classification of motor, Work of generator, 2point 3point and 4point stator, nuclear power plant etc)... Waiting for your reply or videos all the best 😍

standard QAM can be viewed on a 2 dimensional graph. there are modulations that use at least 8192 QAM, and you can add more independent properties to QAM like circular polarization, helix, or spin polarization to make a much denser 3 or 4 dimensional data compression/ modulation wireless link. its just not really done yet, too expensive or not developed effectively enough. its easier for people to move to terahertz waves (IR light up through green light usually) to increase capacity instead of make all available use of the existing spectrum. healthier for us that way anyway.
lol for your quadrant examples you really need to provide a 3 dimensional graph of your sine wave showing one with the waves propagating vertically along the y axis with the second wave propagating horizontally on the x axis overlapping each other. especially since these are what gets referred to as the G in your 2g 3g 4g etc. 5g I believe gets a little different and was why it needed so much more power when compared to the other speeds. and ALOT more emitters since the wave would not propagate near as far, lol hence the controversy from of lot of people that claim sensitivity to wifi signals. i was in school learning all of this stuff right as 5g was being developed so it wasn't really in any of our courses or books but we did go over it in class a couple times. otherwise great video!!!!!!
Hi I am following you from Egypt and admire your content but there are people who can not speak English can support videos by translating to Arabic Thank you.
This is probably like the 3rd time I am seeing someone say that we cannot transmit sounds in their original frequency because the antenna would be too big. It makes me think, wouldn't transmitting it in it's original frequency mean that you're simply amplifying the sound and playing it back on a speaker? Seems to me that transmitting sound through the air, SILENTLY and for a further distance, is the bigger goal of modulation.
Thanks for explanation, yes by 6 Gigahertz it goes faster and QA modulation is better in transfer data. Kind regards, any reaction ? like a command on this subject !
How is signal added to carrier wave? What exactly occurs in the spot where they are added together? Why does carrier wave change just because because signal is added to it? What device is used to add the carrier wave and the signal wave together? What happens at the other end, how is signal extracted from the composite waves, how is done and by what?

The best channel for tech-animated videos with a concrete & concise concept. Thanks for giving us such creative contents !!
Obviously, the best video in internet that is explaining the all concepts briefly.
actually I always take very much good knowledge from this channel almost every video, great thanks to you guys.

As telecom employee this video helps me a lot to understand the telecom basics
The only channel that makes me feel smarter and stupider at the same time
ASK/PSJ/FSK=>1 bit at a time.
16-QAM=>4 bits at once(4 times faster)
64-QAM=>6 bits at once(6 times faster)=>Used in 4G.
Can you do a video on Fourier series how helpful in communication systems?
No need.. It'd be useless since '3blue1brown' has made a perfect one ;)
Zaki Benbouzid We want it on this chanel...not the one you speak of
Irish Muscle you dare question blue brown?
@@irishmuscle7352 Man this channel is for engineering, 3 blue1brown made perfect videos on Mathematics part, making another would be redundant
Simply stated, it helps us to get the components of a signal. e.g. a square wave(digital signal) constitutes of many sine waves(analogue signals).

ONE OF THE BEST CHANNEL TO LEARN THE CONCEPTS
Very intuitive explaination, Thank you for making these videos, and keep making 🙏🙏👌👌
This video has been very helpful in visualizing modulation techniques and it's advantages

They have to be the OGs though ngl
Awesome. Weldone weldone guys. U just helped me remove a long obstacle
appreciating the illustration facilitating the understanding thank you.

Well explained. Thank you.
I'm degree of ict thank you alot information 🙏 ☺
Thanks a lot. You are doing a very noble thing.
thanks very much. i learn more from you about technology .
6:56 64bit data use 8 bit at a time not 4, btw video is fantastic 👍🏻👍🏻👍🏻
fantastic content
Amazing as usual, thanks!
Combining this video with HCV is the best thing to do to learn it in a decent depth.
Super 👍👍 I satisfied
Very very helpful and interesting.
Keep it up
Better than our bored lecturer 👑✊🏿.
Well Explained!!
Thanks for this good content!

Amazing videos you make!
What a beast! SO well explained:)
Kindly upload more videos about communication
please explain about ↘90°phase shifter ↙
*Merci bien pour ce cours, bien illustré!*
Never thought you would resort to click bait...it's great vid nevertheless
Awsome explanation 👍
I really like your ICT topics.Can you Explain me How phase Modulation is done .Thank !
It's so well explained!
Super amazing video 😊😊👏
Thank you sir for your packaged information
very good job! flawlesly explaines
Can you do video on milli meter wave communications. And how its related to 5g communication.
Very good explained
great sir ...
thanks for uploading such video....
Very interesting, very informative, factual; why the hell are there dislikes for this?🤣
Good video sir👌👌

Thanks Lesics Team :)
So grateful.
You taught us how QAM works, cool. Routers with QAM feature and 4G :D
How good it is !
Awsome explanation!
What book do you recommend for a person that's interested in such things ( as an introduction to telecomunication technology) ?
Thanks for explanation, yes by 6 Gigahertz it goes faster and QA modulation is better in transfer data.
Kind regards, any reaction ? like a command on this subject !
Keep doing this kind of video..
I will have to watch this again, very interesting but complex.
I can't say anything. Astonishing🥳🥳😍
life saver 🙇🙇🙇
You are the best thanx
Clear explanation again, thanks. Perhaps the modulation can become faster by combining the data in pairs.
To let the output be resulted by pulses and give the output more hertz, the data can become faster
The QAM part was tricky but understood
Thank you for that great videos
Make more series like these !
Awesome video
The video is awesome. My only complaint is the mobile phone lady is too distracting.
Thanks in advance 🙏
Greetings... Please a video to explain with the functional analog to digital converter.
Brilliant, thank you! :)
Well done bro .
Good lesson
Pretty pictures, nice images. Beautyfull girls☺and many of green plants ☺
What engineering field would you say will be the best one to pursue in about 5 years time 🏆📐
Biotech/neuroelectric integration is my guess
electrical engineering as always, with an obvious minor in computer science;)
You came for 1:04
focus neo.
@Aiden Pearce Yes you did
Nice video
interesting how well intended was the knowledge and how devilishly it got interpreted and propagated

Thank you so much!
Great video but i think that i must start again by video 1 :)
1:20 something tells me you don't really mean 'exactly'
Nice video👍

Can you explain HUM MODULATION?
