Definition 定义 |
Sampling rate 采样率 |
Number of times an analog signal is sampled per unit of time. The unit of time is generally 1 second. Example: 100 samples per second
每单位时间内对模拟信号进行采样的次数，时间单位一般为1秒。 示例：每秒 100 个样本 |
Sampling frequency 采样频率 |
Sampling of an analog signal with respect to 1 second. Specified in Hertz [Hz]. 模拟信号采样约1秒。以赫兹 [Hz] 为单位指定。
Examples: 示例: •Sampling an analog signal once per second corresponds to a sampling frequency of 1 Hz. 每秒对模拟信号进行一次采样对应于 1 Hz 的采样频率。 •Sampling an analog signal once per millisecond corresponds to a sampling frequency of 1 kHz. 每毫秒对模拟信号进行一次采样对应于 1 kHz 的采样频率。 |
