Bandwidth commonly refers to:
*
Bandwidth (signal processing)
Bandwidth is the difference between the upper and lower Frequency, frequencies in a continuous Frequency band, band of frequencies. It is typically measured in unit of measurement, unit of hertz (symbol Hz).
It may refer more specifically to ...
or ''analog bandwidth'', ''frequency bandwidth'', or ''radio bandwidth'', a measure of the width of a frequency range
*
Bandwidth (computing)
In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth.
This definition of ''bandwidth'' is in contrast to the field of signal ...
, the rate of data transfer, bit rate or throughput
*
Spectral linewidth
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. It may result from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used ...
, the width of an atomic or molecular spectral line
Bandwidth may also refer to:
Science and technology
*
Bandwidth (linear algebra), the width of the non-zero terms around the diagonal of a matrix
*
Kernel density estimation
In statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on '' kernels'' as ...
, the width of the convolution kernel used in statistics
*
Graph bandwidth
In graph theory, the graph bandwidth problem is to label the vertices of a graph with distinct integers so that the quantity \max\ is minimized ( is the edge set of ).
The problem may be visualized as placing the vertices of a graph at distin ...
, in graph theory
*
Coherence bandwidth
Coherence bandwidth is a statistical measurement of the range of frequencies over which the channel can be considered "flat", or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are like ...
, a frequency range over which a channel can be considered "flat"
*
Power bandwidth, a frequency range for which power output of an amplifier exceeds a given fraction of full rated power

Bit rate
In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time.
The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction ...
