DPCM编码,简称差值编码，是对模拟信号幅度抽样的差值进行量化编码的调制方式.-DPCM coding, referred to as difference coding is to sample the analog signal amplitude to quantify the difference between the modulation coding.

MATLAB 程序，基于GUI界面设计的PCM调制、编码的仿真，这个是用界面设计开发，为大家在编写程序提供了帮助-MATLAB program, PCM modulation, coding simulation-based GUI interface design, this is the interface design and development, provide help in the preparation of the program
