Signal-generator
- 信号发生器是指产生所需参数的电测试信号的仪器。按信号波形可分为正弦信号、函数（波形）信号、脉冲信号和随机信号发生器等四大类。信号发生器又称信号源或振荡器。各种波形曲线均可以用三角函数方程式来表示。能够产生多种波形，如三角波、锯齿波、矩形波（含方波）、正弦波的电路被称为函数信号发生器。-Signal generator is to generate the required parameters of the electrical test signal equipment. Sinusoida

DSPII_USTC_01
- 传统的宽带信号中抑制正弦干扰的方法是采用陷波器(notch filter),为此需要精确知道干扰正弦的频率.然而当干扰正弦频率是缓慢变化时,且选频率特性要求十分尖锐时,则最好采用自适应噪声抵消的方法.下图是用一个二阶FIR的LMS自适应滤波器消除正弦干扰的一个方案。该代码实现了以下功能： 1) 借助MATLAB画出了滤波器的误差性能曲面和误差性能曲面的等值曲线； 2） 给出了最陡下降法以及LMS算法的计算公式； 3） 用MATLAB产生了方差为0.05, 均值为0白噪音S(n)，并
