基于自回归（ＡＲ）与自回归滑动平均（ＡＲＭＡ）模型，讨论了两种有色噪声的软件生成方法，可使输出序列无起始瞬变现象。给定功率谱函数结构时采用递推算法；给定滤波器系数时采用步降法。分别给出了滤波器的两种设计流程。通过设置滤波器的初始状态，使得在白噪声激励下滤波器的输出序列稳定，无起始瞬变现象。该方法在实际工作中得到应用，软件仿真表明两种设计方法都能满足仿真的设计要求。
Based on the autoregressive (AR) and autoregressive moving average (ARMA) models, the methods of generating two kinds of colored noise software are discussed, which can make the output sequence without initial transients. The recursive algorithm is used for the structure of the power spectrum function, and the step-down method for the given filter coefficient. Two design flows of the filter are given respectively. By setting the initial state of the filter, the output sequence of the filter under white noise excitation is stable with no initial transient phenomenon. The method is applied in practical work. The software simulation shows that the two design methods can meet the design requirements of the simulation.
