What is the difference between transmission bandwidth and channel bandwidth?
The transmission bandwidth refers to the range of frequencies that are being transmitted from one point to another. The channel bandwidth on the other hand refers to the frequencies of a given channel.
What are two primary communication resources?
transmitted power and channel bandwidth
A communication channel with additive white gaussian noise has a bandwidth of 4kHz and SNR of 31dB. Its channel capacity is?
20kbps
How do you calculate spectral efficiency?
1.Find the Fourier Transform of the pulse used to transmit data over the channel. 2.Determine the bitrate of the signal by the modulation format (QPSK for example has 2bits/symbol so 1 symbol per second would equate to 2 bits/s) 3.The first null in the Fourier transform is the required bandwidth (~0.75 x bitrate in optical communications, depends on channel) 4. Divide bits/s by the required bandwidth to find the spectral efficiency.
What is the relation between the bandwidth and symbol rate?
the channel capacity (information in bits per second) is related to bandwidth and SNR by the relation C= B[log(1+SNR) b/s log is at the base 2 B= bandwidth of a channel C= capacity in bits per second SNR= signal to noise ratio.
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
What is the difference between transmission bandwidth and channel bandwidth?
The transmission bandwidth refers to the range of frequencies that are being transmitted from one point to another. The channel bandwidth on the other hand refers to the frequencies of a given channel.
What are two primary communication resources?
transmitted power and channel bandwidth
What are Advantages of delta modulation?
The delta modulation transmits only one bit for one sample. Thus the signaling rate and transmission channel bandwidth is quite small for delta modulation. The transmitter and receiver implementation is very much simple for delta modulation. There is no analog to digital converter involved in delta modulation. The disadvantages of delta modulation are slope overload distortion and granular noise. These are the two drawbacks of delta modulation.
What are key factors that can affect channel capacity?
Channel capacity - It is the rate at which the data can be transmitted over a given path, or channel, under the given conditions. Key factors affecting the channel capacity are- Data rate- speed of data transmission measured in bits per second. Bandwidth – Maximum. Bandwidth, noise, and error rate.
What is the effect of reducing the channel bandwidth?
I'm afraid you will need to specify on what exactly are you referring to. We could be talking about a radio channel bandwidth, a computer data transfer channel bandwidth or even a radio communications channel bandwidth. It is difficult to tell with the narrow question you posed.
What is Low pass channel and band pass channel?
Low pass channel or medium with the bandwidth that starts from zero.Band pass channel has the bandwidth that does not start from zero.
WHAT IS coherence bandwidth of radio channel?
The coherence bandwidth of a wireless channel is the range of frequencies that are allowed to pass through the channel without distortion.
What happen if the bandwidth of signal greater than channel bandwidth?
distorttion
What is the difference between wideband and narrowband?
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
What was the effect of reducing the channel bandwidth?
lesser data traffic
What is the typical bandwidth of a channel for a cable modem?
6 MHz
