1The ratio of the strength of an electrical or other signal carrying information to that of unwanted interference.
信噪比
Example sentencesExamples
Maintaining a high signal-to-noise ratio requires high-sensitivity position detectors and low-noise electronics.
The greatest challenge to the wavefront-coding system occurs when the object signal is very weak, resulting in a lower signal-to-noise ratio in the acquired image data.
Also, by decreasing the microphone gain, any clipping that might otherwise occur as a result of the user speaking more loudly is avoided and the signal-to-noise ratio is not thereby decreased.
When sounds are presented in a background noise, their audibility depends not only on the level of the signal, but also on the signal-to-noise ratio, the ratio of the level of the target signal to that of the background noise.
A dual-feed antenna is installed at the customer premises to capture signals from separate paths and combine them to maximize the signal-to-noise ratio at any frequency.
1.1informal A measure of how much useful information there is in a system, such as the Internet, as a proportion of the entire contents.

Example sentencesExamples
This makes it generally difficult to infer cause-and-effect relationships-the statistical signal-to-noise ratio is rather low.
The group as a whole has an incentive to keep the signal-to-noise ratio low and the conversation informative, even when contentious.
As we ponder what to do about the disinformation inundation, we must consider the fact that we are really dealing with the old broadcast engineering problem of signal-to-noise ratios.
I'll go one further though, and say this about the practice: it's really damaging the signal-to-noise ratio of content I otherwise love.
The idea seemed interesting, but the signal-to-noise ratio was awfully low.
Definition of signal-to-noise ratio in US English:
signal-to-noise ratio
nounˈsɪɡnəl tu
1The ratio of the strength of an electrical or other signal carrying information to that of interference, generally expressed in decibels.
