matlab 误差与范数 现行版本较少 吉林大学应用数学学院老师讲稿 今后会陆续上传(matlab error and norm of the current version of Applied Mathematics, Jilin University, Institute of fewer teachers will continue upload the script in the future)

关于锁相环路的相关仿真，描绘的是一阶锁相环，二阶及三阶的各个特性。(PLL simulation, depicted is a first-order phase-locked loop, the second-order and third-order characteristics.)

Matlab Simulation for Comparison of Different QAM Constellations and Mapping for a Channel with Additive White Gausian Noise

粗糙集的基本算法，包括数据补齐，属性约简，值约简，规则生成，非常实用。(Rough set theory is a new mathematical approach to imperfect knowledge. The problem of imperfect knowledge has been tackled for a long time by philosophers, logicians and mathematicians. Recently it became also a crucial issue for computer scientists, particularly in the area of artificial intelligence. )

说明：  录制一段个人的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用双线性变换法和窗函数法设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)
