| 摘 要： | 分析了纳秒脉冲条件下微分型、自积分型电容分压器的必要条件。用最小二乘法求得了测量系统的冲击 响应,并根据输入波形预测系统输出,采用基于Wiener滤波的反卷积法重建输入电压脉冲,并与积分器的输出波 形对比。结果表明,波形重建的效果要优于积分器,且不受电压等级、频率及采样频率的影响。

| Abstract: | The necessary condition of differential type and self integrate type of capacitive voltage divider under nanosecond pulse is analyzed. The impulse response of measurement system is calculated by the least square method. The output is forecasted by the input waveform and the impulse response. Deconvolution based on the Wiener filtering is used to reconstruction the input voltage impulse. The result proves that this method of waveform reconstruction is superior to that of the integrator and it is not influenced by different voltage level and frequency as well as the sampling frequency. |
