该程序是关于AMI码单极性归零码单极性不归零码等数字基带码型的仿真程序，有GUI界面(The program is about the AMI code is not unipolar RZ unipolar and other digital baseband NRZ pattern simulation program, a GUI interface)

it is useful to generate gaussian random process...... which is the most requirred at the time of simulation.

适合初学小波变换的同学，小程序演示了怎样显示小波各级各频段(show the frequency of wavelet)

sigma-delta DAC simulink model

录制一段自己的语音信号，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。(Section of their own voice recording 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 bilinear transformation design of filters, 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 voice signal Finally, the design of a signal processing system interface.)

HI ..This is soft decision decoding for convolutional coding...nice and good code.

文件为采用matlab进行多项式拟合的程序及其详细讲解(File using matlab polynomial fitting program and explain in detail)

用Matlab演奏经典曲目卡农、最炫民族风、青花瓷、新贵妃醉酒，很多歌曲都可以使用此方法(Using Matlab played classics Canon, and most unusual national wind blue and white porcelain, New Drunken Beauty, a lot of songs can use this method)

对信号加窗，进行短时傅里叶变换，输出一个结构组，包含时间和频谱幅度(Signal windowed short time Fourier transform, and output a structure that contains the time and spectral amplitude)
