Thanks for this very easy to understand refresher of modulation concepts. Had read them some 25 years ago and didn't require them until now. This proved to be to the point introduction of these concepts.
There are 2 types of modulation. Frequency which is 90 degrees. Amplitude which is 180. F demodulation 270. Band spectrum is the push of one over another of cycles.
Sir is there any baseband signal that doesn't need any carrier signal to transmit?? like if we are talking a person face to face and conveying information, or message is there any transmitter in air??
It has been already covered in the subsequent videos. Please check the playlist. ua-cam.com/play/PLwjK_iyK4LLArUHRm3SvPLT0XWlVhpl4h.html&si=vfHJx77KPwY3Mj94
Please clarify. Modulation, we use to transform low frequency signal into high frequency signal so that it can reach upto long distance. Confusion is that high frequency applications like mmWave, visible light communication are operational at short distances. 🤔 what is the relation here of frequency with the distance? Am I ignoring any other parameter? Communication expert, Please response. THANK-YOU
Certain frequencies get absorbed by air. Generally, lower frequencies travel farther because few elements in air will absorb the wavelength. Note, stoichometric spectroscopy can be used to determine with frequencies any given element/compound will absorb/reflect.
thank you so much for the amazing video !! @ 4:13 you said each signal is modulated at different carrier frequency does this mean, it is an FM modulation? or regardless of the modulation type? there will be always a change in frequency?
I like your explanation but... I face problem with finding videos... Please decide videos in to groups.. Like this videos are from this subject.. Etc...
Because in PCM, the message signal is analog signal. Of course the output of PCM is digital signal (in form of 1s and 0s), but the input signal is analog signal. I hope, it will clear your doubt.

Can i know what are the applications of these different type of modulations too?
Wow man this is such interesting topic I love it.😃👍
thank you sir , you make the best video's related to electronics in the whole youtube
That was very clear, thank you. What about modulation index and the calculations....

Its been 15 years since my fear to basic communication principles. And then i landed on to this video.
Thanks helped Alot
for my Last semester of Masters !
Extreme useful video. This talk about everything I'm looking for more than 5 years! You are my hero!
This video is one of the greatest i've ever seen, thanks a lot! You rock!
I am ur big fan i see every video of urs
Any CSE students 🔥❤️
@@unais.sultan yesss

The original signal can in fact be transmitted directly, but the carrier wave lets us move it around to different parts of the radio spectrum.
Thank you!
Nice to meet very most valuable channel on UA-cam about electronics
Full syllabus in one video ❤️
Indeed excellent work sir👍🏻👌🏻
Clearly explanations. What a video
good one helped in my semester exams
evry single topic that I wanna understand it I find an Indian person explain it...I love India bro❤️❤️❤️❤️

Mouth is the transmitter, I stand to be corrected.

So message signal is the same thing as baseband signal? Great video btw. 👍🏼
Yes, they are same.
@@ALLABOUTELECTRONICS ok thanks. 👍
Simple and precise.
Like this video, very detailed, summarized and informative 🫶☺️. Thank you.
nice sir.
Nice Tutuorial Sir, What software do you use
I'm still getting confused by madulating signal and message signal are those same or different plz respond any one
Excellent Video! Thanks a lot!
Excellent 👌 sir
is it possible to point out in detail when and where modulation changes, digital to analog wave form - Digital 1 to analog and Digital 0 to analog.
Excellent 👍
Thank you so much :)

hey, 6:07 for FM, doesn't the frequency of carrier signal increase with increase in frequency of baseband signal? -- how is it amplitude?
What you are saying is correct. And the same is also shown in the video at 6:40. Please re-look it.
Thank you. Gilbert
velly good explianed!
Upload the next lecture soon
Please short summarise in the last of each video!
2:10 why modulation required
Usb modems and some phones have an external antenna connector, useful for those, who are far away from the provider’s box.
Make a video on Wireless communication , gsm , network security
Nice Explanation... Can you provide PPT of this video?
Great Experinced
Sir , i have an question
Why amplitude modulation has range in hertz where as frequency modulation has range in megahertz
Great !!
Any EEE student?
Thank you sir.
Thanks sir👈
planning to go to cumpus but
how can we basically difeciate between properties and the types of modulation can i say they are the same
thank you so much for the amazing video !! @ 4:13 you said each signal is modulated at different carrier frequency does this mean, it is an FM modulation? or regardless of the modulation type? there will be always a change in frequency?
To my considration there is always indeed a change in frequency, otherwise there would be no transmitting.

amazing, it helped me alot
Sir where can i get slides, can u share please
Sir pulse code modulation is digital pulse code modulation how could it be analog pulse code modulation plz explain
Because in PCM, the message signal is analog signal. Of course the output of PCM is digital signal (in form of 1s and 0s), but the input signal is analog signal. I hope, it will clear your doubt.
