# Signal-to-Noise Ratio
|
|
is defined as some variation of $$ \frac{P_{signal}}{P_{noise}} $$.
|
|
In analog, e.g. radio voice communications, it thus describes how clearly the desired signal is distinguishable from noise/interference.
|
|
|
|
In digital communications, it determines the maximum possible amount of data that can be reliably transmitted
|
|
as stated by the Shannon-Hartley theorem. |
