Uncertainty of national standard parameter based on NTN technology is discussed detailedly in the dissertation.
通过对信号波形的逐步处理可以获得波形转折点的位置，以此为基准点可以实现位移的精测。
We find that they can be properply identified by gradually processing the waveforms and the precision measurement of displacement can be implemented based on them.
为补偿波形直流偏置电压，放大器对2.6V内部模拟地基准进行缓冲，并驱动用作LVDT模拟地回路的输出管脚。
To compensate for the waveform's dc-offset voltage, an amplifier buffers the 2.6V internal analog-ground reference and drives an output pin that serves as the LVDT's analog-ground return.
