not to be rude, but...duh...

anyway, thanks for the information, i want to do soem more research on this, though. It has always intereted me how you get picture on your TV just from electonic cables, or how sound can be picked up from radio wave signals.
Well remember, the same signals that go across telecommunication lines and cable tv lines aren't the signals that pop up on your TV or telephone speaker or what have you. The signals are interpreted by electrical equipment that tells, in a television for example, a system of projector, magnets, and other things how to display an imagine using actual light thatyou can see. In radio's case, again, your electrical device, ie your radio, picks up radio waves and interprets them into signals that run the speakers which are actually responsible for creating sound.
