Why do we need modulation during transmission?

[@ykzghtvo8059]

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!

[@sunnyclassroom24]

You are welcome! I am glad it helped you to remember it.

[@zidanetribal2343]

That is Mr. Sunny's gift, turning complex topics into simple but on point explanation :)

[@Tertioptus]

an "analogy" itself is analog transference of data, hence the name

[@arinkarthik4115]

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

[@sunnyclassroom24]

Thanks a lot for your compliment and encouragement. I do my best to provide some useful service to the learning community.

[@se2702]

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

[@erikpoephoofd]

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!

[@sunnyclassroom24]

Thank you very much for watching and making very nice feedback. Good luck with your test.

[@mohamade3110]

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

[@Nawwar1980]

Wow, this man is incredible. Thank you.

[@mc6jumper891]

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

[@aerodynamico6427]

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

[@chotu-tv-12]

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

[@hekk_tech5975]

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

[@sunnyclassroom24]

Glad you like them!

[@manjularaja9460]

The best analogy seen ever. 😊👍

[@blackwalker4157]

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

[@mehwishsultan8116]

Wow! what a explaination thank you...

[@abu-bakrjabbarov7942]

Explanation with very good examples!

[@sunnyclassroom24]

thanks.

[@EdwardHood]

Sunny. Keep up the great work!

[@sunnyclassroom24]

Many thanks for your kindness. I will.

[@anesbel2213]

It's very powerful explanation , thank you very much.

[@sunnyclassroom24]

@@anesbel2213 Thank you very much for your kind comment. Happy 2019 Year!

[@karthik14141]

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.

[@PatelJitendrabORN2sUCCEED]

Great Examples. thankyou

[@DopetheKid]

so thankful for your videos sir

[@Yazan-studio]

perfect way of explaining itt thank you Doctor\Sir

[@alexsmth8925]

Now i understand, why we need modulation!

[@sunnyclassroom24]

Glad to help!

[@mouctechy]

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

[@georged8138]

very good explanation - thank you!

[@raisonjiriyengwa1308]

this is great. well explained

[@parthapratim6274]

You are amazing Mr. Sunny

[@sunnyclassroom24]

Thank you very much, Patho.

[@fikret8422]

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...

[@sunnyclassroom24]

Thank you very much again for your encouragement. I will try my best to make more videos. What you have said are very encouraging to me. I try to be simple because my English is not good. I put subtitles simply because my accent might confuse some users.

[@maxwellchiu6859]

Incredible lecture.

[@soumallyapal7333]

Hats Off Sir... ❤❤❤

[@skskd4995]

Brilliant explanation for student like me

[@sunnyclassroom24]

Glad to hear that

[@perfectpakka8151]

@ 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?

[@sunnyclassroom24]

you can say rock is the message. however, paper does not help if we wrap it with a paper and throw the stone.

[@verdiernoyama9681]

Thanks a lot. It was really helpful

[@yokeleetan8525]

u are amazing. i love e simple explanations

[@sunnyclassroom24]

Thank you for your time! Check out my other videos please!

[@istiaquekhan2023]

Sir, You are great

[@sunnyclassroom24]

Many many thanks

[@MyLukson]

Wonderful

[@sharuniharajendran1541]

Awesome!!!

[@asifurrahman5436]

So good explanation

[@alexsmth8925]

Thank you!

[@sunnyclassroom24]

You're welcome!

[@iqraamin1001]

EXCELLENT

[@BENMADANIHoussemEddine]

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

[@PU5MLF]

Muito ótimo explicação! Parabéns.

[@amodamatya]

Why is low frequency wave more susceptible to interference??

[@lochanahansini5700]

Thank you so much❤

[@ricarteo]

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

[@wafa8858]

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

[@sunnyclassroom24]

You're welcome!

[@陈冠男]

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.

[@hamadhalbahrani8781]

thank you so much

[@vhavuk3901]

very nice.

[@sunnyclassroom24]

Thanks a lot!

[@avinashgore5617]

nic explanation....:)

[@yvesprogrammeur]

you are the best

[@jayadalja5746]

(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?

[@mostaqueahmed6595]

Thank you so much SIR

[@emmanuelgenerale2821]

Thanks

[@cck0728]

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

[@ajohpv7033]

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

[@reshmahittalamani9608]

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. .

[@direnb3401]

Any videos on QPSK?

[@hamidali2583]

What about different Hf signals /VHF signals

[@pavankumarenugula5637]

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

[@dhruvneo]

@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.

[@sunnyclassroom24]

Thank you for pointing that out. No, it has nothing to do with the distance. It is an analogy why we need carrier wave to modulate our original data.

[@sheelasony8069]

Awesome animation sir. Which app do you use for animation

[@sunnyclassroom24]

Flash

[@hamidali2583]

How signal powerful Hf or vhf
