'''科学术语'''

采样频率，也称为采样速度或者采样率，定义了单位时间内从[[连续信号]]中提取并组成[[离散信号]]的采样个数，它用[[赫兹]]（Hz）来表示。采样频率的倒数是[[采样周期]]或者叫作[[采样时间]]，它是采样之间的[[时间间隔]]。通俗的讲采样频率是指计算机单位时间内能够采集多少个信号样本。<ref>[https://baike.baidu.com/reference/1494233/533aYdO6cr3_z3kATKDYxKrxZCjFN9Svv-HXB7FzzqIP0XOpX4fuU8Y_4tYz9_UpFwTG_49ra99aHw9N3NvCO2m6pk2D．mbalib ,引用日期2016-04-14]</ref>
