In general, the Shannon-Hartley equation applies to any communication channel with a known bandwidth. For example, a device such as a cable modem may have a very high SNR ( > 1000) but a fairly narrow bandwidth. The Data Over Cable Service Interface Specification (DOCSIS 3.0) requires that the downstream per-channel bandwidth of a compliant cable modem must be either 6 MHz or 8 MHz wide. These are specific examples of how logarithmic functions are used in science.

• Research using the library or the Internet to find a specific example of how exponential and logarithmic functions can be applied to IT.
• How are exponential and logarithmic functions related?
• What is a key point on the graph when shifting exponential or logarithmic functions?
• When shifting exponential or logarithmic functions, what are key guidelines that can help shape the graph?
