distinguish btwn signals of same frequency and different data

[ANSA THOMAS]

Is it possible to split signals having same frequency but different information at receiver side??Like am using two arduino boards to recieve signals seperately,but both correspond to same frequency and data is different..is it possible to distinguish between the two signals and extract each without interference?

Hi there,

Signals at *exactly* the same frequency would be very difficult to distinguish from each other. The only way that I could think of to do it would be some sort of time-division multiplexing. See the following Wiki page to get you started: https://en.wikipedia.org/wiki/Time-division_multiplexing

It may be somewhat complex though, I'm not sure what your skill level is or what level of resources you have available in order to accomplish your project.

Good luck!
James

If you are using analogue, then you need to use the I/Q method. But you need to do this on transmission. This is how the colour signal was (is?) sent on PAL TV transmissions.

I worked with a high quality large intercom system that used time-division multiplexing to have up to 8 people and/or background music on one path. Then it had many paths. I modified it slightly for a major airport paging system so that its frequency response was -3dB at 15kHz and its noise and distortion were very low. The consultant wanted hi-fi response at the airport and my design won because we were the only bidder who could do it.
