The Signal-to-Noise Ratio (SNR or S/N) is a measure that compares the level of a desired signal to the level of background noise. It is commonly used in various fields such as telecommunications, audio engineering, and data transmission, and is a crucial parameter for assessing the quality of a system. Here’s a more detailed breakdown: 1. **Signal**: This refers to the information or data that is intended to be transmitted or processed.

A signal-to-noise ratio compares a chosen measure of a signal with the corresponding noise measure. For a constant measured electric potential difference and a root mean square noise voltage , an amplitude ratio is ; the corresponding power ratio under equal electrical resistance is its square. State the convention and measurement signal bandwidth, since changing either changes the numerical ratio.
