Adaptive digital filters with variable step-size may become unstable when their weights are automatically adjusted with inputsignal and noise.
变步长自适应数字滤波器的权值随信号和噪声的变化自动调整时可能出现不稳定。

In simulation experiment, results of identifying models using step disturbance of given power signal, white noise signal, and pseudorandom signal as input signals have been compared.
在仿真试验中，比较了给定功率阶跃扰动信号、白噪声信号及伪随机信号分别作为输入信号进行辨识的结果。
