Firstly, in the lower frequency application, R-MOSFET-C filter is used.
首先，对于低频应用，可以使用 R-MOSFET-C 滤波器。
参考来源 - 全集成连续时间滤波器的设计Results indicate that the lower frequency the air-conditioner runs at, the lower heating capacity it produces, the higher COP it possesses. The frequency conversion air-conditioner runs at low frequencies with higher efficiency, which is the main reason of energy-saving.
结果表明:变频空调器的制热量随运行频率的降低而减少,在低频运行时,制热量变化大大减小基本保持不变;而COP值随频率的下降始终呈上升趋势,可见变频空调器在低频运行时经济性较好,这是变频空调器节能的主要原因所在。

It works at a much lower frequency than the infrared sensors, and is less affected by dust particles.
它比红外传感器的频率要低得多，而且较少受到尘埃粒子的影响。
A vibration that has a higher or lower frequency than a sound, he found, tends to skew pitch perception up or down.
频率超过或低于声音频率的震动会分别引起音高知觉的上调和下调。
In fact, due to their lower frequency, at similar RF exposure levels, the body absorbs up to five times more of the signal from FM radio and television than from base stations.
事实上，由于频率较低，在射频接触水平相同的情况下，人体从调频收音机和电视吸收的信号比从基台吸收的信号要多四倍。
