Question:-

Explain how artificial satellites help in transmission of television programs over large areas.

⠀

Solution:-

• The picture and sound to be transmitted is first converted into electrical signals.

• These electrical signals are then converted into a special type of waves and transmitted in air from a transmitting antenna.

• The artificial satellites have special instruments which receive the signals transmitted by the earth stations.

• The signals so received are then amplified and retransmitted, by the artificial satellite that finally reach the television at different areas.

Artificial satellites help in long distance transmission of television programs. The picture or sound to be transmitted is first converted into electrical signals. They are then converted into a special type of waves and transmitted in air from a transmitting antenna so as to reach the artificial satellite. The signals received are then amplified and re-transmitted by the instruments fitted on the satellite. The antennas fixed in a number of stations on the earth including those of cable operators receive the signals and re-transmit them. The television sets receive the signals and reconvert them in the form of images and sound.
