/ˈsɪɡnəl tə nɔɪz ˈreɪʃiəʊ/C1formaltechnical
  • zh原本是电子学和通信领域的术语,指有用信号强度与背景噪声强度的比值。引申义指信息中有效相关内容与无关或干扰内容的比例。

A technical term originally from electronics and telecommunications, referring to the level of a desired signal compared to the level of background noise. In broader contexts, it is used metaphorically to describe the amount of useful or relevant information compared to irrelevant or distracting content.

  1. Technical measurementC1formal

    A measure used in science and engineering that compares the level of a desired signal to the level of background noise.

    • The signal-to-noise ratio of the audio recording was too low to hear clearly.
    • Engineers improved the signal-to-noise ratio by using better shielding.
    • A high signal-to-noise ratio is crucial for accurate data transmission.
  2. Data qualityC1formal

    In information theory and computing, the ratio of useful information to irrelevant or false data.

    zh信噪比

    • The signal-to-noise ratio of the dataset was poor due to many duplicate entries.
    • Filtering algorithms can improve the signal-to-noise ratio in search results.
    • A low signal-to-noise ratio makes it hard to extract meaningful insights.
  3. Metaphorical useC2informal

    Used informally to describe the proportion of useful or meaningful content versus irrelevant or distracting content in a discussion or environment.
