In modern electrometers, the preamplifier output terminal is such a point, and can be used to reduce the effect of cable leakage, as shown in Figure 2-5.
在现代的静电计中，前置放大器输出端就是这样的一个节点，并可以用来降低电缆泄漏的影响，如图2 - 5所示。
The research on the module of preamplifier, A/D voice input, D/A voice output, and controlling of the system is laid stress on.
重点研究了系统的前置放大模块、A／D音频输入与D／A音频输出模块，以及系统控制模块。
