Why modal dispersion limits the fiber bandwidth?
In a multimode fiber modal dispersion causes each mode to have a different velocity and reach to the end of the fiber at a different time. This will cause inter-symbol interference (ISI) which means that we need to send data at lower rates in order to prevent ISI. Lower rates means a reduction in bandwidth.
What is despersion?
Dispersion is an abstract quality of a sample of data. Dispersion is how far apart or scattered the data values appear to be. Common measures of dispersion are the data range and standard deviation.
Dispersion is the degree of variation in the data?
No
What does dispersion indicate about the data?
correlation which can be strong or weak
What has the author Floyd Buckley written?
Floyd Buckley has written: 'Tables of dialectic dispersion data for pure liquids and dilute solutions' 'Tables of dielectric dispersion data for pure liquids and dilute solutions' -- subject(s): Dielectrics, Dispersion, Solution (Chemistry)
What important feature of the data set is not revealed through the different measures of centre?
The dispersion of the data.
What does the mean absolute deviation tell you about a set of data?
It is a measure of the spread or dispersion of the data.
What measure of dispersion is used with bimodal distribution?
Central tendency is used with bidmodal distribution. This measure if dispersion is similar to the median of a set of data.?æ
Why standard deviation is best measure of dispersion?
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
Is data transmitted faster by fiber-optic or satellite?
Fiber Optic.
What are the whiskers of a box plot?
They are some measure of the dispersion or range of numbers in the set of data.
Why measures of dispersion are important along with measures of central tendency to understand the nature of the data?
Central tendency will only give you information on the location of the data. You also need dispersion to define the spread of the data. In addition, shape should also be part of the defining criteria of data. So, you need: location, spread & shape as best measures to define data.
