How to transfer signals

    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.
