通信原理课程设计脉冲编码调制（PCM）系统摘要：脉冲编码调制（PulseCodeModulation），简称PCM。是数字信号是对连续变化的模拟信号进行抽样、量化和编码产生。PCM的优点就是音质好，缺点就是体积大。PCM可以提供用户从2M到155M速率的数字数据专线业务，也可以提供话音、图象传送、远程教学等其他业务。关键字：脉冲编码调制、取样、量化、编码、解码Abstract:Pulse Code Modulation (PulseCodeModulation), referred to as PCM. Digital signal is a continuous change in analog signal sampling, quantization and coding production. PCM sound quality is good advantages and disadvantages are bulky. PCM can provide users from 2M to 155M line speed of digital
