A proper integral filter is designed to parallel with the Fourier system Thus the influence of DC offset on impedance calculation is cancelled.
傅里叶系统并联一个适当的积分滤波器以后可以消除非周期分量对阻抗计算的影响。

Firstly the carrier phase with frequency offset is obtained with a parallel method.
该算法利用并行方法估计有频差时的载波相位。
3
The principle of stiffness offset with the positive and negative stiffness parallel were introduced and through analysis the natural frequency and the vibration transmissibility can be reduced.
