| 摘 要： | 提出了一种基于时域加权的新的非叠代优化算法,用于重构经过采样示波器测量的阶跃信号、脉冲信号等。该算法构造了一个期望误差函数,由于这个期望误差函数与真实误差很接近,因此构造了新的价值函数,并使用时域加权来优化不同的波形,在减小时域振铃时有效的控制噪声放大。与误差能量,归一化方法相比,该算法经过仿真实验表明了其可行性和有效性。

| Abstract: | A new non-iterative algorithm with time-domain weighting is described for reconstructing fast,step-like,or impulsive signals that have been measured with a sampling oscilloscope.The approach uses a new non-iterative filter optimization that is based on a calculated "indicated error" function that is similar in shape to the true error,and it permits the use of time-domain weighting to optimize the measurement of different waveform features,to control noise amplification while minimizing time-domain ringing.The performance of the proposed approach is compared with that of the Error Energy/Regularization approach that is current popular. |
