A cheap builtin audio chip is likely to have some sort of lowpassfilter in its amp to avoid smoking itself though.
一个廉价的内置音频芯片可能有某种在放大器的低通滤波器,避免吸烟本身虽然。

A damping circuit is a type of lowpassfilter that reduces the electrometer's ac response so the low DC current can be measured accurately.
该衰减电路是一种降低静电计交流响应的低通滤波器,使我们可以准确地进行直流弱电流的测量。

The simulation result shows that the dynamic response and the detection precision in detection circuit can be greatly influenced by the cut-off frequency, order and type of lowpassfilter.
