What describes a signal with a frequency of 20 GHz in satellite radio transmissions?
A downlink signal A Ka Band signal
What is up converter in satellite communication?
Every information sent and received through satellite communication has to have an address to enable the communication process of signal delivery and reception. This naming of the signal is made in the form of a specific frequency. For example each TV channel operates on a unique frequency of it's own. When that frequency is called (tuned technically) out of a spectrum in that band, the chosen frequency gets selected. Since satellite transponders operate at very high frequency, modulation of the signal on to the carrier is difficult. Hence modulation is carried out at a much lower frequency. Such modulated signal is raised to the required frequency( name or address as stated above) that supports the satellite band and the transponder. The equipment used to elevate the frequency of the low frequency carrier (known as Intermediate Frequency) to the satellite transponder frequency is UP CONVERTER C.K.Vasudeva Bangalore
Why is electricity transmitted at low frequecies?
The higher the frequency, the shorter the signal travels with the same relative transmit power. With lower frequency the signal travels longer. That's why you can listen to radio's from around the world, but not tv transmissions.
Why won't a satellite TV in-line amplifier boost a DTV signal in a fringe area?
Most likely it's because the satellite amplifier doen't have the bandwidth or frequency range to cover the DTV signal.
How can you block the transmitter signal?
Transmit another signal using the same carrier frequency to interfere with the original signal...also known as "jamming". If you have two signals using the same carrier frequency, and you add a second signal source with the same carrier frequency, and an a stronger amplitude (intensity), but different signal data, then it mixes with the original signal at the receiving end, and the original signal cannot be clearly decoded.
Describe how a network based VoIP provider interacts with the PSTN?
PSTN will convert the digital signal from VoIP into voice signal. Their networks interacts using satellite frequency.
What is the speed of a satellite signal?
A satellite signal will be a radio signal. And a radio signal in space travels at the speed of light.
Is rg6 coax cable the best to use for satellite tv in home?
For Dish Network, we use RG6 coax cable to allow a higher frequency range for the satellite signal from the dish to your receiver. Any coax cable not rated at RG6 could affect the signal.
How are signal received in radio station?
transmissions
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
What is the purpose of resonation?
Resonance describes a 'condition' rather than a 'purpose', but it is made use of in (for example) radio circuits, in order to tune the radio to a particular frequency (the resonant frequency of the signal).
When low frequency signals added to high frequency signal then the envelope signal will follow which signal?
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
