    Okay.. i need to get my head around this that

    instead of transmitting an electric current that only changes when the value of a bit changes, long-distance communication systems usually send a continuously oscillating carrier signal modified according to the information to be transmitted.

    I dont understand why this is...

    Can anyone help me out?

    If you only transmitted 1's, how would you know if you haven't lost signal?
