摘要:

本文以一个双声道声码器为例,来说明线性预测编码技术在处理语音信号中的应用.一个2400b/s,双声道线性预测编码的声码器,使用高速、可编程序的位片型微处理机,字长可扩充.并使用2K的RAM和1K的ROM的数据存储器.该系统设计成循环时间为208毫微秒的双总线结构.该声码器能同时处理两个声道,用微处理机和线性预测编码技术开发出该系统,并叙述使用该技术设计声码器的要领.

Abstract:

This Paper takes a two-channels vocoder as an example,to explain the linear predictive coding(LPC)technique applied to the speech signals processing.Using high speed and programable bit-slice microprocessor established a 2400b/s two-channel LPC vocodor,and word length can be extensible.The data storage of 2K RAM and 1K ROM uses.The system cycle time is designed with 208x10~(-9) sec two-bus structure.The vocoder processes two-channels concurrently.By microprocessor and LPC technique the system was developed,and essentials which design vocoder used by this technique described in this paper.
