  • zh在将模拟信号转换为数字信号时，每秒钟采集的样本数量，通常以赫兹（Hz）或千赫兹（kHz）为单位。

The number of samples of an analog signal taken per second during conversion to a digital signal, typically measured in hertz (Hz) or kilohertz (kHz).

  1. Digital audio frequencyB2formal

    The number of samples of audio carried per second, measured in Hz or kHz, used to convert analog sound to digital.

    zh采样率

    • A standard CD uses a sampling rate of 44.1 kHz.
    • Higher sampling rates capture more detail in the audio signal.
    • The engineer adjusted the sampling rate to improve sound quality.

  2. Data measurement frequencyB2formal

    The rate at which data points are collected from a continuous signal to convert it into a discrete digital signal.

    zh采样率

    • The sensor's sampling rate was set to 100 Hz for accurate readings.
    • A low sampling rate can cause aliasing in the recorded data.
    • The experiment required a high sampling rate to capture rapid changes.
