How is frequency division multiplexing implemented on hardware?

[nitin_zilch]

how do we transfer many electrical signals of different frequency over a wire?

i know its called frequency division mutiplexing, but i want to know how it is implemeted on hardware.

There is a better thing called, orthogonal frequency division multiplexing, your ADSL.

Take a look at this. It explains in-depth the implementation of such division. The only difference between this one and you mentioned is that carriers are orthogonal to each other.
