At last, the paper also presents three different applications of the sorting processor to electronic warfare: detection of threating signal, filtering of useless signal and PRF selection filtering.

最后介绍了分选预处理器在电子战中的三种应用：威胁信号检测、无用信号滤波和脉冲重复频率选择滤波。

It also USES "adaptive filtering" technology, where electronic filters lock onto sound waves and remove them, even if the wave's amplitude and frequency change as the drill is being used.

该设备还采用了“适应滤波技术”。即便声波的振幅和频率在牙钻使用之时发生了变化，电子滤波器仍能锁定声波并将其转移。

Capacitors are essential components of virtually every type of electronic equipment. They are widely used for bypassing, coupling, filtering, and tuning electronic circuits.

电容器是各种电子设备中的基本元件，广泛地应用于对电子电路进行旁路、耦合、滤波和调谐等。

Unlike two-way, three-way, four-way or so-called "hybrid" armature driver (hearing aid type) earphones, there are no electronic or comb filtering artifacts, no phase issues, and no crossover dropouts.

The other is to block the electronic path to objectionable material with filtering software.
