Detailed explanation-1: -The correct answer is MF. MF(Medium frequency) band is not used for satellite communication.
Detailed explanation-2: -Ku-band (12–18 GHz) Used for satellite communications. In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra.
Detailed explanation-3: -The correct option is C Noise. Explanation:Noise is not a component of communication system.
Detailed explanation-4: -Internal combustion engines: Satellites do not use internal combustion engines because they require oxygen to operate, and there is no oxygen in space. Instead, satellites typically use electric propulsion systems, such as ion thrusters, to maneuver in orbit.
Detailed explanation-5: -Among the given options, radio waves are used for satellite communication. Q. (a) Arrange the following radiations in the order of their increasing wavelength : X rays, infrared rays, radio waves, gamma rays, and micro waves.
Detailed explanation-6: -The downlink frequency in the C-band transponder is about. Statement A: Satellite communication uses different frequency bands for uplink and downlink. Total band of frequencies allocated for satellite communication is spread over. More items
