Multiple choice evs - i communication and mass media understanding communication and impact of mass media satellites in communication importance of transport system artificial satellite

How do you describe the complete signal path of the satellite communications operation?

  1. Begins at a ground station, proceeds to an uplink, then to a downlink, and ends at a receiving ground station.

  2. From the satellite, to a downlink, then to a ground station

  3. Begins at a ground station, proceeds to an uplink, to the satellite itself, to a downlink, and ends at a receiving ground station

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A communication satellite works like a relay station where signals transmitted by the ground stations are picked up by the satellite's receiver antennas(uplink), the signals are filtered, their frequency changed and amplified, and then routed via the transmit antennas(downlink) back down to Earth.

Multiple choice evs - i communication and mass media understanding communication and impact of mass media satellites in communication importance of transport system artificial satellite

In which of the following communication methods, the transmitted and receiving antennas can be oriented in any direction?

  1. Ground Wave propagation

  2. Satellite communication

  3. Sky wave propagation

  4. Space wave propagation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The direction of transmission and receiving are both fixed in ground wave propagation, sky wave propagation and space wave propagation. However in satellite communication, the antennas are oriented in the required direction depending upon the position of satellite, so that the beam is aligned with the satellite.

Long range transmission of TV-signal is done by

  1. space wave

  2. sky wave

  3. ground wave

  4. artificial satellite
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

TV-signal ( $30: MHz$ - $300:MHz$) are not reflected by ionosphere. Therefore, sky-wave propagation is not possible and similarly ground and space wave is also not feasible. Hence, they are transmitted to artificial satellite from where they are transmitted back to the Earth.

Reception of information involves

  1. decoding of signal.

  2. storage of signal.

  3. interpretation of signal.

  4. all of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The received signals is either AM or FM so it needs to be demodulated, ie., decoded to get back original signal. It also needs to be stored and interpreted at receiving end.
