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

Great video. The bit about phases really cleared up a mental block I had.

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.

@ultrameticulous Ай бұрын

Good info. Do you have a recommendation for a video which accurately visually depicts the AM/FM electromagnetic field?...waves?

@SttmpJohnson Ай бұрын

@@ultrameticulous There is a pretty good video on KZfaq 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 KZfaq of varying quality and you can always use one of the search engines as well. Hope this helps.

@abdifatahmohamed8600 19 күн бұрын

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 KZfaq 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"

@LiquidMetal64 14 күн бұрын

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??

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.

Animations are top notch. However, the narration was off topic and background music was too loud

Just depends what is modulated on to them.

I’m pretty sure modern day modems use quadrature amplitude modulation. That’s also what LTE and 5G use.
