引言本文介绍一种适合于语音信号处理和进行计算机模拟的数据采集板,它可插在IBM—PC微型计算机(或其兼容机)的扩展槽中,对语音信号或频带范围近似于语音的模拟信号进行数据采集,同时它还具有数字信号到模拟信号的转换功能以及对模拟信号输入和输出的滤波性能。该板特别适合于大专院校从事语音信号处理的同志,因为它使用简单,价格最便宜。§1、什么叫PCM编译码器
INTRODUCTION This paper presents a data acquisition board suitable for speech signal processing and computer simulation that can be plugged into an expansion slot in an IBM-PC microcomputer (or its compatible) to simulate a speech signal or band that approximates speech Signal data acquisition, it also has the digital signal to analog signal conversion function and the analog signal input and output filtering performance. This board is particularly suitable for comrades engaged in speech signal processing in colleges and universities, because it is simple to use, the cheapest price. § 1, what is PCM codec
