1.   The electrical problem arises from the finite time it takes a signal to travel across a chip.

2.   The signal travels over the cable network.

3.   But not all the signal travels by ground wave.

4.   DSL signals travel at a higher frequency over the same wire and do not interfere with phone calls.

5.   FM signals travel only by air, but AM signals travel by ground and air.

6.   Most important is the increase in bandwidth that speeds the flow of data between computers and allows video signals to travel the Internet.

7.   No home rewiring is needed, because signals travel through existing wires in the wall.

8.   Once there, video signals will travel over either copper or coaxial cable to a video set-top box.

9.   Signals travel in a straight line, so those from towers have a limited range on the curved surface of the Earth.

10.   Signals travel from the master clock to the pineal gland and other centers that release hormones throughout the body.
