Question

state in brief how artificial satellites are used in transmitting television programmes over large distances

Answer 1

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.

Answer 2

HI MATE,

ARTIFICIAL SATELLITES HELP IN LONG DISTANCE TRANSMISSION OF TELEVISION PROGRAMS. THE PICTURE WAS FOUND TO BE TRANSMITTED IS FIRST CONVERTED INTO ELECTRICAL SIGNALS. THERE THEN CONVERTED INTO SPECIAL TYPE OF WAVES AND TRANSPARENT IN AIR FROM A TRANSMITTING ANTENNA SO AS TO REACH THE ARTIFICIAL SATELLITE POINT THE SIGNALS RECEIVED AS AN AMPLIFIER TRANSMITTED BY THE INSTRUMENTS FITTED ON THE SATELLITE. THE EMPTINESS FIXED IN A NUMBER OF STATIONS ON THE EARTH INCLUDING THOSE OF CABLE OPERATORS RECEIVE THE SIGNALS AND RETRANSMIT THEM. THE TELEVISION SETS RECEIVE THE SIGNALS AND WE CONVERT THEM INTO FORM OF IMAGE AND SOUND.


HOPE THIS HELPS YOU.....☺☺☺☺
