说明：  （7，4）循环编码m文件基于matlab(（7，4）convenc encoder m file base on matlab )

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.)

模拟信号线性调制系统设计,Simulink的使用方法，能熟练运用该软件设计并仿真通信系统dsb,vsb,ssb(Linear analog signal modulation system design, Simulink use can skilled use of the software design and simulation of communication systems dsb, vsb, ssb)

模型是进行控制与稳定性分析的基础，可以服务于仿真、系统行为分析、系 统内在机理分析、控制、预测、监督与故障诊断等目的。因此，建立系统的模型 已成为许多科学研究与工程实施的首要问题。(Model is the basis for control and stability analysis, can serve simulation, system behavior analysis, the internal mechanism of the system analysis, control, forecasting, monitoring and troubleshooting purposes. Therefore, the establishment of the system model has been implemented for many scientific and engineering the most important issue.)

说明：  三相电压型整流器控制，控制方法是模型预测控制，可以在simulink上完美运行。(The control method of three-phase voltage source rectifier is model predictive control, which can operate perfectly on Simulink.)
