从互易性偏置调制的机理出发，将对本征频率的测量转化为对无效调制光功率响应的尖峰脉冲的测量；根据光功率响应机理，将对半波电压的测量转化为求有效调制光功率最小值。
The method comes from the mechanism of reciprocal shift modulation, which transforms the measuring of eigenfrequency into measuring the spike pulse responding to ineffective-modulation optic power.
讨论了获得脉冲电流的原理。实测波形显示，输出的矩形波脉冲电流非常精确，且带有前沿尖峰，有利于电弧的稳定。
The wave shape measured indicates that the converter outputs the exact square pulse current with a peak in each front edge of pulse which is the benefit for arc stabilization.
虽然落空啦某些QRS波尖峰旌旗灯号地高频重量，可是重建地旌旗灯号与注入波形地本来外形契合得相当好。
While losing some of the high frequency components of the QRS spike, the reconstructed signal conforms rather well to the original shape of the injected waveform.
