Term: Signal-to-Noise Ratio

Description:

The signal-to-noise ratio refers to the ratio of the desired signal to the background noise in any given system. It is widely used in various fields such as electronics, telecommunications, and data analysis to assess the quality and reliability of a signal.

Senses:

1. Technical Definition: In electronics, the signal-to-noise ratio represents the power level of an electric signal compared to the level of unwanted noise.
2. Data Analysis: In data analysis, the signal-to-noise ratio measures the strength of a desired signal against the interference from irrelevant or random data.
3. General Usage: The term "signal-to-noise ratio" is sometimes used figuratively to describe the clarity or quality of information in a given situation or communication.

Examples:

Example 1 (Technical):

In an audio system, a higher signal-to-noise ratio ensures clearer sound reproduction without the interference of background noise.
