如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.
这些误差源包括热电动势、由射频干扰(RFI)经过整流而产生的偏置量以及电压表输入电路中的偏置量。
These sources include thermoelectric EMFs, offsets generated by rectification of RFI (radio frequency interference), and offsets in the voltmeter input circuit.
为了补偿由于惯性敏感元件高频振动整流所引起的非线性输出误差，研究一种新的补偿方法——随机采样法。
In order to compensate the nonlinear errors induced by the rectification for high frequency vibrations in the inertial measure unit (IMU), the paper presents a new random sampling method.
