Bandwidth

Bandwidth is the maximum amount of data that can be transmitted over a network or communication channel in a given amount of time.  It's often measured in bits per second (bps), such as kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps).  Bandwidth is like the width of a highway, the wider the highway, the more cars (or data) can travel on it at the same time.

With internet connections, higher bandwidth means that more data can be transferred at once, which can result in faster download and upload speeds.  However, bandwidth doesn't always reflect the actual speed of a connection since other factors, like network congestion or device performance, can affect data transfer.

 

Bandwidth (Data Transmission) formula
\( B \;=\; D \;/\; T \)     (Bandwidth) \( D \;=\; B \; T \) \( T \;=\; D \;/\; B \)
Symbol	English	Metric
\( B \) = Bandwidth	\(bits\;/\;sec\)	\(bits\;/\;s\)
\( D_v \) = Length of Span	\(GB\)	\(GB\)
\( T \) = Transmission Duration	\(sec\)	\(s\)

 

Bandwidth (Signal Processing) formula
\( B \;=\; f_{high} - f_{low} \)     (Bandwidth) \( f_{high} \;=\;  B +  f_{low} \) \( f_{low} \;=\; f_{high} - B \)
Symbol	English	Metric
\( B \) = Bandwidth	\(bits\;/\;sec\)	\(bits\;/\;s\)
\( f_{high} \) = Highest Frequency	\(Hz\)	\(Hz\)
\( f_{low} \) = Lowest Frequency	\(Hz\)	\(Hz\)
