Bandwidth

The maximum amount of data a connection can transmit in a given amount of time. This concept is conceptually different from Bandwidth in the DSP context

Shannon’s Channel Capacity Theorem

Shannon's Channel Capacity Theorem

The maximum Data Rate $C$ achievable over a channel of Bandwidth $B$ with a given Signal-to-Noise Ratio is:

$$\begin{array}{rl}C& =B{\log }_2(1+\text{SNR})\\ C& \propto B\end{array}$$Link to original
