一种基于声卡的载波台语言信号采集系统的研制

The Manufacture of a Sampling System of Line Carrier Speech Signal by Using Sound Card

在讨论了声卡技术特征和载波网络接口的基础上 ,提出了一种利用计算机声卡采集载波台语言信号的新方法。该系统结构简洁、操作方便、构思新颖、通用性强 ,可实现长时间、大容量的数据采集 ,克服了传统载波台语言信号采集系统功能单一的缺点 ,可广泛应用于各种载波通信场合。同时 ,大大拓展了声卡的应用领域。

On the basis of technical property of the sound card and line carrier network interface.A new method about line carrier speech signal by using a sound card is put forward.The system has merits of simple structure、facility operation、novel idea, it can carry out lots of time and large capacity data sampling and overcomes a disadvantage of simple function in the traditional line carrier speech signal sampling system.Moreover, The line carrier speech signal greatly developed the applied area of sound card.
