Definition

Noun: - Signal-to-noise ratio: A measurement, often expressed as a ratio, that compares the level of a desired signal to the level of background noise. It is a key metric for assessing the clarity or quality of a transmission, recording, or data set.

Usage
  • s/n is primarily used in technical and scientific contexts, such as electronics, telecommunications, audio engineering, and data science.
  • It is often written in its abbreviated form "s/n" or "SNR". The abbreviation is typically not used in possessive forms or pluralized.
  • Example:

  • Signal-to-noise ratio: The full, unabbreviated term.
  • Noise floor: The measure of the signal created from the sum of all noise sources and unwanted signals.
Synonyms
  • Signal-to-noise ratio (full term)
  • SNR (initialism)
Antonyms
  • There is no direct single-word antonym. The concept is often described inversely as "poor quality," "low clarity," or "high noise level."
Related Phrases
  • Improve the s/n: To take actions that increase the ratio of signal to noise.
    • Example: Using a better antenna can significantly improve the s/n.
  • s/n degradation: A decrease in the signal-to-noise ratio.
    • Example: Over long distances, s/n degradation is inevitable.
Noun
  1. the ratio of signal intensity to noise intensity
