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.
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??
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.
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.
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?
Hello, I would like to simulate an amplitude demodulation in the spectrum. Do you know a simulation program with which I can simulate it? Many thanks and best regards Gislain
@@ALLABOUTELECTRONICS excellent video, which helps traine and trainers But kindly explain with working circuit please,it will motivate, thank you keep it up.
Modulating wave is the message signal. The carrier signal changes its amplitude/ frequency according to the message or modulating signal. The modulated wave is the resultant signal after the modulation. The modulation could be AM, FM, PM etc. But the resultant wave after the modulation is called modulated wave. I hope, it will clear your doubt.

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 RUclips about electronics

Mouth is the transmitter, I stand to be corrected.
Great...Perfect explaination....
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.
very nice and it's clear to understand 10q sir,

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.
👏👏👏 beautifully explained.
Can you please tell, how do you animate your videos 😃😃😃

I'm still getting confused by madulating signal and message signal are those same or different plz respond any one

I think theres an error in the modulated signal of the PSK.
The represatation of the first two "1"'s differ from each other, is that correct?
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.
thanks you listed clearly
Thank you Sir for explaining beautifully. can you please share me analog and digital communication ppt
great videos it is very useful thank you so much....🤗
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.
Nice Tutuorial Sir, What software do you use
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
explanation very well thank u

Isnt PCM a method to convert analog to digital? Why it is under analog modulation?
The signal which is being modulated is analog signal. That's the reason.
