What is the typical bandwidth of a satellite transponder?
38 MHz. digital bit-rates vary depending on compression, modulation, typically QPSK. Expect at least 30 Mbps.
Double conversion transponder?
In a double conversion transponder , the signal received from the ground station is converted into IF , then the signal is filtered & amplified . Finally the IF signal is again upconverted to desired frequency and transmitted downwards.
Will sunspots have a direct effect on digital TV?
Yes, at least twice a year as the sun crosses the equator. March and September, if I recall, correctly. What happens is that the sun appears directly behind the satellite and the electromagnetic energy over powers the transmitting part of the transponder on most satellites. The electromagnetic energy more or less `piggybacks' itself on the carrier signal at the same time, becoming part of the satellite's transmitted signal and rides that signal back to earth where it presents itself as 'noise'.
What is the meaning of transponder?
The word transponder is a combination of transmitter and responder. It is generally defined as a device which transmits a signal upon receiving a signal. It may be used as a beacon, as a signal repeater, an identification device, or any of numerous other uses.Please see the Wikipedia for an overview of the concept.
How do you draw a satellite link in a computer schematic?
Graphically you'd draw a stylised satellite (in orbit) and satellite dish (on the ground), with a dashed line between the two. If the dish is both transmitter and receiver, use arrowheads in both directions. If it is a receiver only, arrowheads should point from the satellite to the dish.
What is the first passive satellite transponder?
echo 1
How does satellite technology use a transponder?
Satellite technology uses a transponder to receive sings and then transfer them to satellites in other locations. They are used for purposes of space satellites and GPS.
What is the frequency range in satellite communication?
The satellite transponder typically works in either the C-band (4-8GHz) or the Ku-band (12-18GHz) and these are for the downlink (from the satellite to the earth station).
What is the receiving and transmitting device called that is inside a communication or broadcast satellite that relays received signals back to Earth?
downlink
Which transponder on Direct TV satellite 7s is used for local stations in Jacksonville Fl?
check out lyngsat.com for a list of sats transponders channels and frequencies
How do you get SKY satellite TV in Belize?
With a satellite dish, a satellite receiver, a satellite PC card, you can watch satellite tv shows on your pc. It effectively replaces the set-top box with higher quality and flexibility. The signal will be more stable and you can have more initiative.You might use the TV tuner card, such as TBS DVB-S PCI tuner card, it allows user simultaneously receive dual DVB-S2/S TV channels, this enables the user to watch one channel from one transponder/satellite while recording another channel from a second transponder/satellite. Alternatively the user can use one channel for data download while watching TV on another channel at the same time

How do you determine if a transponder key is bad for your car?
Locksmiths have transponder detectors that read if a transponder is active within a key. The device we have is called "TD3AII Transponder Detector" by Ilco.
Does the key for the 2000 Daewoo leganza have a transponder?
The Daewoo had NO transponder on any of their vehicles from 1999-2002. Incorrect. The Daewoo Leganza had a transponder option in 2001+, as did the Lanos. The Nubria had a transponder option in 2000+.
Were is transponder for door locks locate on 1994 Pontiac grandprix?
