1.   Because light waves have a high frequency, modulated light can carry signals of wide bandwidth.

2.   They consist of a copper core, which carries the signal, surrounded by a braided mesh of fine copper wire.

3.   Those signals are carried from nerve cell to nerve cell by chemical messengers called neurotransmitters.

4.   A thin cable carries the signal to a computer.

5.   The axon of the cell is the fibre that carries signals out from the cell body to the dendrites of other nerve cells.

6.   Among other things, that means building more antennas to carry signals from point to point.

7.   Andrew Johnson, a spokesman for TCI, noted that the cable company is obligated by law to carry signals from each of the Bay Area stations.

8.   As a result, it takes more towers to carry the signals.

9.   Atlanta-based Cox Communications also stopped carrying the signal of Fox stations in suburban Washington, D.C. and Cleveland.

10.   Bell Atlantic still must win approval from the Federal Communications Commission on a market-by-market basis to upgrade its cable systems to carry video signals.
