cutofffrequency

中英词典

cutoff frequency [ˈkʌtˌɔf ˈfrikwənsi] (名词) 1. (电子学) 截止频率，截止频率是指信号频率超过该频率时，电路的输出电压或功率下降到一定程度的频率。 2. (信号处理) 截止频率，截止频率是指信号频率低于该频率时，信号的幅度下降到一定程度的频率。 cutoff frequency (形容词) 1. 截止频率的，与截止频率相关的。

词语辨析

截止频率 (cutoff frequency) 和临界频率 (critical frequency) 有时会混淆使用，但两者有细微的区别。截止频率是指信号频率低于或高于该频率时，电路或信号处理的输出会有明显变化；而临界频率则是指信号频率达到该频率时，发生某种特殊现象或变化。
