| 摘 要： | 脉冲编码调制(pulsecodemodulation,PCM)是概念上最简单、理论上最完善的编码系统,是最早研制成功、使用最为广泛的编码系统。运用软件方法来实现PCM编解码芯片的部分功能并与PCM编解码芯片相结合来共同完成整个电路设计上的编解码,不仅设计简单,灵活方便,而且往往可以达到事半功倍的结果。本文介绍用Matlab的Simulink来仿真实现PCM编解码器的方法和过程,此方法具有简单,直观等优点。

| Abstract: | Pulse-code-modulation(PCM) is a coding system with the most simple conception and most perfect theory. And also , it is coding system which has been successfully developed , widely used . Using software to realize some functions of the PCM coding-decoding chip and combining software with chip to accomplish the coding-decoding function in the whole designing will not only make the whole system designing simple and flexible, but also help us to achieve an indescribable perfect result. In this paper, the method and process of realizing PCM coder-decoder by Matlab's Simulink toolbox are described. This method has some advantages, for example, it is simple and immediate. |
