- Data transmission starts with electromagnetic waves, but how do those waves really make data move? Learn how modulation makes data transmission possible.

RUclips algorithm is doing its job very well.
nah
Great video. The bit about phases really cleared up a mental block I had.
Nice, easily understandable and adding to knowledge without leaving too much out. thank you for the nice video.
Great video on the topic, plus the animations really help visualize these topics
easy, clear, concrete, just as it must always be. Congratulations
That's a good video; simple and clear! thanks!
Very well done. Adding this to my video collection for new hams! Thanks.
awesome video, just what I was searching for!
among many grungy videos, this one is great...clear...perfect
I was just reading about this but the animations were key to understand it, many thanks
Very underrated video. Thank you so much!
Wow I'm really impressed with the effort of simplified concept and beautiful animation
thank you thousand times for this informative video .
Damn this was so very well done.
excellent explanation!!!
I liked the video before watching. What technology did you use?
Well explained sir!!
Excellent video for HAM Radio Technical License (the 1st license we get)
Great video always underrated.
Great video
Good video, but the music is too loud and distracting.
No it's not
No it's not
@@SubSilenceYeah it is
Just turn the volume down
I wish i could comprehend a little bit what the guy explained.
enlightening
I just learned so much👍🏻🇺🇸
Unfortunately this video continues to give the false impression that an electromagnetic wave actually constantly goes up and down, up and down, up and down as it travels forward through space. In actuality, the sine wave shape is just a graphical representation of the intensity of the electric and magnetic fields of the wave as it travels through space.
Good info. Do you have a recommendation for a video which accurately visually depicts the AM/FM electromagnetic field?...waves?
@@ultrameticulous There is a pretty good video on RUclips called “What is an electromagnetic wave?” as part of the “Physics Made Easy” series of videos. It doesn’t have anything to say specifically about amplitude or frequency modulation, but it gives a good introduction to how the sine wave shape is used to represent the intensity and direction of the electric and magnetic fields. There are many other videos on this subject of course on RUclips of varying quality and you can always use one of the search engines as well. Hope this helps.
i don't think so. Sound waves are depicted as 'Sine curves' and 'Transverse' in most books with amplitude showing the intensity of loudness. I don't think that undermines the fact that they are longitudinal and they propagate parallel to their motion as its mostly made clear. The subsequent diagrams after the base understanding is to bring the idea closer to the mind of the learner. Its much easier to visualize frequency and wavelength of any 'wave' using a sine curve representation, otherwise, the video didn't even mention the details you're saying...
@@SttmpJohnson idk why RUclips didn't display your comment. I had to click your account to see it. I understand the concepts. I was referring to what you said, looking for a true visual depiction versus a graphical representation. I actually stumbled on one shortly after asking you. "How does an antenna work - ict #4"
I didn’t do any research but I always knew it doesn’t make sense for a wave to move up and down.. I really need more info on this, could you please recommend me a video or article to explain what is actually happening??
What an amazing video, too much information zipped together. Well modulated.
This great video made for some easy learning! I wish this was how science was taught back in school =(
best!
Gorgeius
Just depends what is modulated on to them.
Animations are top notch. However, the narration was off topic and background music was too loud
We can only see a very small portion of it, between 700 (“red”) and 400 (“violet”) nanometers and when all are perceived at once we call it “white”. Beyond violet there’s UV, bluetooth/wifi/TV/cellular signals and cosmic radiation, and beyond red there’s IR heat signatures, radar and radio signals. Hearing is how we make sense of vibration waves, and vision is how we make sense of radiation waves.
I’m pretty sure modern day modems use quadrature amplitude modulation. That’s also what LTE and 5G use.
Music is too loud
Please tune to 370 Hz to cancel out the music.
“One wave per second” = 1 Hz 😊 0:40
I like the part where you talked about electromagnetic waves💀💀
#Analog-modulation … 1:25
Amplitude is measure of intensity.

Annoying meaningsless music
RF Engineer here. This whole thing is just garbage. If you want to understand how we transmit information by radio waves, please ignore this mess and look elsewhere.
If their intent was to create misconceptions, they hit the mark.
What would you recommend instead?
Bad corporate music.
I wish this is how I was taught in college🥲
Great video
We're glad to hear it was helpful, Pious! -Scott
