| 摘 要： | 当用计算机模拟满足一定功率谱规律的离散数字随机信号时,通常是对伪随机白噪声离散数字信号进行数字滤波来模拟。但由于成形滤波器的输入信号为白噪声,导致数字滤波结果与滤波步长h有密切关系。本文通过实例,给出了一种修正数字滤波步长对模拟结果影响的方法。

| Abstract: | When the random processes that meet certain power spectra are simulated by digital filters to white noise, the step length of the filters affects response mean-square values and correlation functions. The presented methods in this paper can correct the effects of the step length on mean-squared vlues and correlation functions. |
