本课题研制了一种宽频带的数字锁相放大器，可以完成自动增益和相位 可调整，最长积分时间为100s，适合于频率从10Hz到10kHz，幅值从100nV 到10mV的微弱正弦信号检测。测量结果表明，当采样点数N大于8192时， (This project developed a wideband digital lock-in amplifier, can be completed automatically adjustable gain and phase, the longest integration time of 100s, suitable for the frequency range from 10Hz to 10kHz, amplitude from 100nV to 10mV of weak sine signal detection. The measurement results show that, when the sampling point number N is greater than 8192 hours,)

Bit-Error-Rate Simulation Using Matlab

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

这是关于现代信号处理的一些课件，主要讲述了有关离散序列的傅里叶变换等(This is about some of the courseware of modern signal processing, mainly tells about the discrete Fourier transform sequence)

求联合概率密度的matlab编程，可用于大部分数学或曲线拟合的场合(Seek the joint probability density)

用五点差分格式解拉普拉斯方程和用工字型差分格式解拉普拉斯方程，均生生成为函数文件，可以指教调用(By five o clock Difference Schemes for Solving the Laplace equation and labor font Difference Schemes for Solving the Laplace equation, both life and life becomes a function of the file, you can enlighten call)

根据姚天任 现代数字信号处理 第四章，那个课后作业题编的，搞了好久，结果很理想，如果能搞成，1024点，结果会十分稳定。(music method)
