Unipolar signaling using a continuous wave is probably the best approach.

 

Iruka, to start with, you should try building a radio transmitter and receiver. After that you can build an oscillator to hook to the transmitter in order to transmit a continuous wave.

Thanks, i think i will try that!

Are you interested in transmitting digital data, or just video? If your interests are video, there are much simpler analog schemes like NTSC.

 

Your best bet might be to get involved with a local ham radio club and express interest in transmitting video. Would you be more interested in something like this:

I'm sorry, a video was a bad example. No, im not instrested in transmitting video, only high data files, like an exe or zip or rar with a data of 1-3 or higher mb... Im sorry again, that i confused you in to thinking i was wanting to transfer video.

There's several ways to encode digital data into analog media. One of the most common is quadrature amplitude modulation:

 

http://en.wikipedia.org/wiki/Quadrature_amplitude_modulation

 

The data rate is controlled by three variables:

 

1) Bits per quadrature, which represents how much data is encoded into each "symbol"

 

2) Quadratures per second, otherwise known as the baud rate

 

3) Total multiplexed channels. To boost throughput, you can transmit data on multiple frequencies simultaneously

 

Multiply these three values together to calculate total throughput

Ok, this sounds good, but could i show the bottom of my frst post?

P.S. Im relly sorry if i seam like a idoit with this post' date=' but im only 13, so dont be to harsh...

So.. how about english? Sorry if i soud rude, but i cant understand a single thing you said besides: There's several ways to encode digital data into analog media.

Set up Wi-Fi?

The point here is to make my own, so i want to know what EM wave at what frequency ect. i sould use. If i wanted to set up wi-fi, i would use Bluetooth or Netgear...but i want somthig i made...

It's certainly possible. However, I think that using radio would be too slow for "high amounts of data at once" and more trouble setting it up than it would be worth.

Infrared (IR) is a region of EM waves with a higher frequency than radio. I think it would be fairly easy to find an IR port for a laptop. You also have the added benefit of the FCC not hassling you for unlicensed FM broadcast.

Err... But doesent a IR only transfer data at a single point, like this:

-----o

Im looking for a wide range 'wave' like this:

(((*)))

so i can be in any point in the range and still recive data, and also have multiple recivers..

An example that infinity/infinity=anything

 

let a=the total number of integers

let b=the total number of even integers

 

both a and b are infinite but a is twice as large as b

so, a/b=infinity/infinity=2

and b/a=infinity/infinity=0.5

 

The reason we get this is that there are many different ways to define infinity.

Thats like saying:

a/b=c

but with out knowing at least two of the variables, you can solve the problem, but if you have:

b = 2

c = -6

a / b = c

a / 2 = -6

-6 x 2=-12

a = -12

this can be solved, but without knowing b and c, a could be any thing, then the world would be drove insane cuz no one can figure for a.

opps! I did it again, by friends IQ just droped 5 points cuz i damaged his head with a unsovable equation.

Get my point, people only give infinity for an answer, cuz the dont realy know the answer!...or im talking crap, and have no clue what im saying...

Ok, I was wondering if a EM Wave can carry data, I do belive that i heard or read that they could, but I need to know how i could get a EM Wave, more pacificly, Radio Waves, to carry huge amount of data, like a video, not just the small audio waves... I have a little FM Radio Tranmiter, that a radio can pick up, but it can only carry audio files, is it posible to, as above, have it carry high amounts of data at once, and have it be picked up by a laptop with a Radio Adapter?

Thank,

Ok, thanks for the reposts! I apprecate your activity.

Ok, im a starwars fanatic, and as i was playing a game, i notised that the players could apply a shield field and be protected from bullets:eyebrow:. Now i have been doing some research on it and found this fourm, then i search for 'reverce magnet' and found this: Can a magnet be made to PUSH metal? So here i am wondering if you strip pyrolytic carbon to about 2 mm, would it lose any force from the orginal, i don't know, 1 sq. dm block, and, would it have the power to stop a bullet before it hit you?

Thanks,
