A_rate_of_13_c_dc
A率13折线的编译码实现
1、了解PCM及13折线A率编码及译码的原理；
2、随机给出一个语音信号，并用A率13折线PCM对其编码；
3、将编码后的信号经过加性高斯白噪声信道，并在接收端对其进行译码；
4、分别画出原始语音信号、PCM编码信号以及译码后信号的波形。
(A rate of 13 polyline encoding and decoding implementation
1, to understand the principles of PCM and the broken line 13 A rate of encoding and decoding
Two were given a voice signal, and PCM encode A rate of 13 polylines
3, the encoded signal through an additive white Gaussian noise channel, and the receiver decodes
4, respectively, to draw the waveform of the original speech signal, the PCM encoded signal and decoding signals.)

ADPCM
TXT信号的获取：一般都是拿到一个.WAV的信号，用cooledit或者其他的打开，另存为txt格式，注意的是，此时txt文件的前面两行会写入一些采样率的信息，将这几行删掉，程序就可以顺利得读取你保存的txt了。(TXT signal acquisition: generally get a .WAV signal, with coolit or other open, save as txt format, note that at this time txt file in front of two lines will write some sampling rate information, will These lines deleted, the program can be smooth to read your saved txt.)
