摘 要
PCM就是脉冲编码调制的简称,就是现代语音通信中数字化的重要编码方式。本课程设计利用MATLAB集成环境,对信号进行PCM编码调制,建立13折线A律PCM编码器模型,进一步绘制出对信号进行脉冲编码调制时域波形图,根据运行结果与波形分析PCM编码调制,加强对这部分内容的理解并了解如何运用于语音传输,光纤传输等领域在课程设计中,系统开发平台为Windows 2000,使用工具软件为MATLAB 7、1。本课程设计主要目的就是在信号传输过程中,运用A律PCM译码实现数字信号到模拟信号的转换。该设计运用MATLAB的M文件来编写程序,根据经过抽样、量化、编码后收到的码组(极性码除外),使用A律译码产生相应的控制脉冲,从而输出一个与发信端抽样值接近的脉冲,通过计算,得出理论值与实际值近似,成功达到了设计效果。在该平台运行程序完成了对脉冲编码调制以及对结果的观察。通过该课程设计,达到了对信号进行PCM编码的目的。
