Brilliant explanation! Now I will never, never, never forget what modulation is! I will instantly remember a piece of paper and a rock. Explaining complex topics with analogy is a great teaching method. Thank you!

Your method is very good and will help me understand in a logical manner rather than memorizing it. Definitely a noble intent to help out everyone & indeed a service to humanity

Sunny, your paper with rock analogy is absolutely brilliant. I've watch many of your presentations and you an amazing teacher.

You are a genius teacher. Rare and truly a gift. New subscriber.

Sunny, you bring the sunshine into my brain, thank you 🙏🏻

You just nailed it, simple and layman terms unfold all mysteries.Full marks sir!

Brilliant.. Thanks for your work and putting things this simpler. I believe yours is one of the most under-rated channels. I wish you get more subscribers and greater visibility and recognition.

You are really sunny as you explain every thing in easy and very clear way , so thanks and keep the good work.

i truly appreciate u sir.i could never understand these topics without ur help thank u so much god bless u

Wow, this man is incredible. Thank you.

Best Video For Learning Digital Communication, Other Channels just overcomplicate these simple things

very very simple and meaningful thank you, sir, please keep making videos in the field of wireless communication, awesome!

Thank you for the video...it taught me a lot. Thank you Teacher, you has been efficient.

Very well explained. Just the right speed. Congratulations. Upvoted.

The best analogy seen ever. 😊👍

Wow, great explanation! I have a test about Communication Technologies in a week and so I'm very happy with this video! You are a great teacher!

Fantastic Video! Thank you for all your hard work.

Muito ótimo explicação! Parabéns.

Wow! what a explaination thank you...

Hats Off Sir... ❤❤❤

this is great. well explained

great explanation... thank you!

Great Examples. thankyou

Each and every parts are gold.

Explanation with very good examples!

Why is low frequency wave more susceptible to interference??

Saved my networks exam, thanks alot :)

sunny your videos are very powerful, i like the analogies you bring. it is so much easier to remember something this way. thank you very much

Incredible lecture.

EXCELLENT

I greatly appreciate your excellent explanation. what about the concept that says: the higher the frequency, the lower the distance traveled by the signal?

Thanks a lot. It was really helpful

so thankful for your videos sir

So good explanation

Wonderful

This is wonderful video because your sentences are so simple however effective and you support your ideas with great metaphor and also even if your english pronounciation is good you put the subtitle all of them is great thank you so much and please add more video...

Thank you so much❤

Sunny. Keep up the great work!

Thank you for your work, even don't speaking English very well, i could understand all the concepts. I'm from Brazil.

Sir,your explanation is superb. Can you make a video on cdma and sdma.

u are amazing. i love e simple explanations

thank you so much

Excellent video. But how sound waves (chat) are imposed on carrier (radio) waves? Thanks.

Thank you so much SIR

You are amazing Mr. Sunny

Thank you dear Sunny

Thank you!

Tq u sir..easily understood. .but I have one doubt sir..according to ur explanation data signal wave has lower frequency than carrier wave..bt in ur diagram data signal frequency higher than carrier wave. .

nic explanation....:)

I just love you, thank you very much...

Sir, You are great

sunny u light up my day ❤❤😍😍💋💋😉😉💖💖😜😜👏👏💋💋✌✌🤞🤞💕💕❤❤🙌🙌😊😊👍👍

Now i understand, why we need modulation!

Brilliant explanation for student like me

Thanks

@ 1:59 Why can't we say the Analogy in reverse? - Rock is the Message Signal, the internal components of the message depends persons inbetween the phone conversation. We can't tell those persons to speak in a restricted way = Rock shape can't be changed. - Paper is the Carrier Wave, where we can mould/cover it according to the shape of the rock (message) = changing the carrier. Finally, let us recall the basic definition of modulation: *Process of changing the carrier signal properties (such as amplitude, phase and frequency) with respect to the message signal* is analogically equivalent to the *Process of changing (covering) the paper properties (such as thickness, quality, size) with respect to the rock* I think this gives a clear picture... A great fan of Sunny from India 🇮🇳 Am I right Sunny?

very nice.

I'm confused with reason 3. Like 2.4Ghz and 5Ghz wifi,we say 5Ghz will attenuate quicker because it has higher frequency. Then back to lower frequency signal and carrier signal,The carrier should also attenuate quicker because it has higher frequency. In order to receive the weaker carrier signal,I must use a bigger antenna than the antenna to receive low frequency signal.

Sir please made a video on dpcm (differential pulse code modulation)

@Sunny Classroom : One point I would like to make. As per my understanding Modulation with Higher frequency, is to send and receive the signal without any delay. Like a speedy transmission. From your rock example it seems that distance is also one of the factors that is affected. is that so ? Could you please elaborate a little bit ? Thank you.

(1)Why higher frequency wave have more bandwidth? & (2)why lower frequency signals would require a much larger antenna? & (3)why low frequency wave more susceptible for interface than higher frequency?

Any videos on QPSK?

Awesome animation sir. Which app do you use for animation

What about different Hf signals /VHF signals

How signal powerful Hf or vhf

Ada yg kesini karna tugas elerning ?

very good explanation - thank you!
