Bandwidth has several related meanings:

* Bandwidth (computing) or digital bandwidth: a rate of data transfer, throughput or bit rate, measured in bits per second

* Bandwidth (signal processing) or analog bandwidth, frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz

* Spectral linewidth: the width of an atomic or molecular spectral line, measured in hertz

Bandwidth can also refer to:

* Bandwidth (linear algebra), the width of the band of nonzero terms around the diagonal of a matrix

* In kernel density estimation, "bandwidth" describes the width of the convolution kernel used

* A normative expected range of linguistic behavior in language expectancy theory

* In business jargon, the resources needed to complete a task or project

* Bandwidth (radio program): A Canadian radio program

In bandwidth is defined a frequency span - the difference between a high frequency and a lower frequency.

Is low bandwidth signal has more power than high bandwidth signal?

no,because generally the lower frequency side existed for lower bandwidth,and higher frequency side existed higher bandwidth,so thus we can say that lower bandwidth has generally has lower power as compared to higher bandwidth.


What is transmission bandwidth in data communication?

Bandwidth is something like a space; bandwidth is proportional to the signal rate. if the signal rate is low then the bandwidth is high and vice versa. bandwidth carry the amount of information in a specific time period.For example if 1 person travel in 1 car then bandwidth will increase or if 4 person travels in 1 car then bandwidth will decrease. :)

What is the difference between regular and dedicated bandwidth?

Regular bandwidth means you are sharing bandwidth with other people on the network so the more people on the network the slower one's connection will be. Dedicated bandwidth guarantees one a certain amount of bandwidth that is not shared.


What is absolute bandwidth?

Absolute bandwidth is the relative bandwidth of the signal (B) times the center frequency (f0). For example , by increasing the center frequency, the relative bandwidth is unchanged, but the absolute bandwidth is increased due to increasing the center frequency. I hope it is helpful :-)


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.
