1·The author's solution to this problem is to use a tuneable RF preamplifier which also acts as a low pass filter when tuning the low end of the 88-108 MHz band where most of the exotic channels lie.
作者的解决这个问题是使用可调谐射频前置放大器这也渠道作为一个低通滤波器调谐88-108兆赫时，低端的带异国情调的地方大部分的谎言。
2·Have designed the concrete drive circuit of LED light sources and the concrete circuits of preamplifier and subtracter, etc.
设计了具体的LED光源的驱动电路，以及前置放大器、减法器等的具体电路。
3·During the detector and preamplifier acquire nuclear information and WDS convert the analog signals to digit value, the nuclear signals will inevitable be distorted to make the final result worse.
在核探测器和前置放大器获取核信息及波形数字化系统将模拟核信号数字化的过程中，都不可避免地会使核信号发生畸变，影响测量结果的精度。
4·The 12-bit ADC in C8051F020 samples the EEG signal amplified by the preamplifier.
脑电信号通过前置放大器放大后，由C8051F 020内部的12位ADC进行采样。
5·These cards include a built in preamplifier and are controlled through a microchip processor.
这些卡中包含一个内置的前置放大器，是通过一个微芯片处理器来控制的。
