产生典型的几种信号波形，如方波，三角波，白噪声等。-A typical signal waveforms generated several, such as square, triangle, white noise.

扩频通信系统编程~~带高斯白噪声-Spread Spectrum Communication System Programming ~ ~ with a Gaussian white noise

设计一个巴特沃斯带通滤波器，通过加白噪声后，对其进行滤波测试-Design a bart wo bandpass filter, by adding a white noise, the filter test

白噪声经过AR模型的输出作为LMS滤波器的输入，已知：a1=1.558；a2=-0.81；白噪声方差为1.0，均值为0；u＝0.002；利用Matlab实现：-White noise as the input of the LMS filter after the output of the AR model known: a1 = 1.558 a2 =-0.81 white noise variance of 1.0, an average of 0 u = 0.002 using M
