Answer» rtificial 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.If likely plz mark me as brainliest(trying to rank up |
