Satellite Communication Frequency Modulation Is Used Because Satellite Channel Has

The role of satellite communication in education has not been as prominent as commercial broadcasting although telemetry has been in use in education for years. This data has to be frame synchronized using a special hardware. A computer the modem usually has intermediate frequency if output that is 50 200 mhz however.

Question is in satellite communication frequency modulation is used because satellite channel has options are a small bandwidth and negligible noise b large bandwidth and severe noise c maximum bandwidth and minimum noise d high modulation index e leave your comments or download question paper.

Satellite communication frequency modulation is used because satellite channel has.

Data to be transmitted are transferred to a modem from data terminal equipment e g. Other equipment that are essential for creating a satellite link include satellite antennas and frequency converters. The receiver hardware setup must be ready at any time to make it ready it s performance is to be tested continuously the frequency with which satellite data is coming is also continuously tested. Fm is no longer used for tv services and even in data services fm is not really used.

Satellites are usually operate at gigahertz range of frequency and the modulation signals are up converted to the transmission frequency and amplified before going on air the term modulation is also used to describe certain types of baseband processing like pulse amplitude modulation pam or pulse code modulation pcm. In satellite communication frequency modulation is used because satellite channel has. The satellite data received in x band is in a particular data format. Amplitude modulation is used for broadcasting because.

Fm used to be used for analogue tv via satellites because it had excellent noise immunity compared to am and provided a relatively good signal lock. A communication satellite is a repeater between. Small bandwidth and negligible noise b. A satellite modem is not the only device needed to establish a communication channel.

Large bandwidth and severe noise c. Other types of modulation systems use in communication satellite are quadrature systems where the modulated signals are represented in terms of two channels like i and q. Formerly iridium satellite llc is a publicly traded american company headquartered in mclean virginia iridium operates the iridium satellite constellation a system of 66 active satellites and 9 spares in space used for worldwide voice and data communication from hand held satellite phones and other transceiver units. In satellite communication ku band in ghz refers to.

Space telecommunications has also been used for many years by television networks broadcasting live news events and cross continent entertainment shows. Psk is using for satellite communication because psk signal can be transmitted through the non linear channel of a satellite and it depends on the proper choice of the modem filters 5. What is used is phase shift keying psk and sometimes am combined with psk to form qam. An ideal power limited communication channel with additive white gaussian noise is having 4 khz band width.

Maximum bandwidth and minimum noise d.
