一．PCM编译码脉冲编码调制（PCM）是现代语音通信中数字化的重要编码方式。利用MATLAB语音实现语音信号的脉冲编码调制（PCM）仿真，可以为硬件电路实现提供理论依据。通过仿真展示了PCM编码实现的设计思路及具体过程，并加以进行分析。(Pulse encoding modulation (PCM) is an important way of modern digital encoding in speech communication. To realize the pulse modulation encoding of speech signal using MATLAB voice (PCM) simulation, can provide a theoretical basis for hardware implementation. The simulation shows the design and implementation of PCM encoding process, and analyses.)
