录制一段个人自己的语音信号，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，采用窗函数法和双线性变换设计滤波器，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 person s own voice signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and the bilinear transform filter design and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback of voice signal Finally, the design of a signal processing system interface.)

循环冗余校验CRC (Cyclic Redundancy Check)码是由分组线性码的分支而来，其主要应用是二元码字。编码简单且误判概率很低，在通信系统中得到了广泛的应用。循环冗余校验码是属于分组码中的一类重要的线性码，它不仅在理论上具有很好的代数结构，而且其编码和译码可以通过线性移位寄存器很容易地实现。 通过对CRC的分析和基于MATLAB工具的仿真，充分证明了CRC的检错能力很强，编码简单。 (Cyclic Redundancy Check CRC (Cyclic Redundancy Check) code is a linear code from the sub-branch from the main application is the binary code word. Coding is simple and very low probability of miscarriage of justice, in the communication system has been widely used. Cyclic redundancy check code is a block code in one important class of linear code, which not only has good in theory, algebraic structure, and its encoding and decoding of linear shift register can easily realize . CRC through analysis and simulation tool based on MATLAB, and fully proves that the CRC error detection ability of a strong, simple coding.)
