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.)

说明：  源程序中包含PCMu率与PCM线形之间的编解码(source contains PCMu rate between the linear PCM codec)
