I have a question on how data signals are modulated electrically. Now I know that many signals use frequency modulation. That is the data is created by changing the frequency of the signal in a pattern that a receiver can decode into data.

However how are high bandwidth signals modulated in electrical lines? Are they also frequency modulated and the frequency is just extended into the billions of hertz range to accommodate that additional bandwith? Or do they use something other then frequency modulation to create data in a high bandwith electrical signal?

Huh?

I will explain this question later ,but first ,I will post this image. Look at it and tell me if you understand.

There has to ne an interositer at each end of the data transmission system to modulate the signals.



Most important, though, is not to get the red and black wires mixed up.

Now I know what I did wrong -- I twisted the red and black together! >f

Don't listen to Slack. He's doing a psychological experiment on the effects of lack of sleep on the bwain... brain. He got me roped in somehow, and now I can't sweep... sleep.

Always remember the flux capacitor. The flux capacitor is key.

Yeah, you and your "smart bombs"


Edit: SPL Tech , you should probably request a moderator to move this thread to the hardware section

And standing with one foot in a bucket of water gets rid of any unecessary electrical resistance
