How is the channel used in the digital communucation system?
The channel used in a digital communication system is used to convey an information signal. A channel has certain capacity for putting in information that is measured by bandwidth in Hz or data rate.
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.
Why it is generly true that a digital signal required high bandwidth than analog signal?
A: Analogue signal Direct voltage that varies in the low spectrum of frequency on digital signal the information is deciphered in micro seconds therefore the frequency must be hi the higher the better.
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
What is the general purpose of a bandwidth meter?
It measures the bandwidth, or amount of data, which a user has used. This is useful for companies which have limits to the amount of bandwidth they have sold, or who sell bandwidth at a price per gigabyte.
Why is bandwidth more economical than digital?
This question doesn't make sense.
What is the voice-grade bandwidth for digital voice channels before compression?
64 Kbps
What is shanon capacity?
digital bandwidth = analogue bandwidth * log2 (1+ SNR) where SNR = strenthe of signal power/ strength of noise larger the SNR it is better.
Bandwidth of digital signal is infinite?
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
The effect of different bandwidths on a digital bit?
None. A bit is a bit is a bit, and all are digital. Bandwidth identifies how much space is available for bits.
Will digital tv become anything like cable because it has extra bandwidth which can be used to broadcast more channels?
In reality, digital TV doesn't have extra bandwidth. It uses the same (or a little less) amount of bandwidth as standard NTSC television signal, but since it's digital in nature, they are able to multiplex up to eight TV signals within the same amount of transponder space. So yes, it can broadcast more channels.
What is the difference between bandwidth and bit-rate in web steaming?
Bandwidth:- It is one characteristics that measures network performance is bandwidth. Bandwidth can be measured in two values:- 1. IN HERTZ 2. IN BITS/SEC. Bit Rate:- It is used to describes digital signals. the bit rate is the no of bits sent in 1s
What is the use of digital multiplexers?
The use of digital multiplexers is mainly on increasing the amount of data that a network can receive on a certain bandwidth and time. It is also called the data selector.
Whose bandwidth is high digital or analog?
it could be either one, depending on application. need more information to answer.
The telephone line the bandwidth for the voice is usually the bandwidth for data?
Because voice communication uses more information to reproduce the person's tones and qualities over the line. Data is a digital signal composed of 1 & 0 - needing much less bandwidth.
Voice-grade bandwidth for digital voice channels before compression is?
it depend on the number of bits that used in adc used
What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
