一种高精度中频信号数据采集卡的硬件设计

The Hardware Design of a High-precision IF Signal Data Acquisition Card

该文介绍了一种基于软件无线电思想而设计的高精度中频信号数据采集卡。对比传统数据采集卡，给出了一种新型的数据采集卡设计方案。实验表明，该数据采集卡很好地解决了传统数据采集卡在信号处理带宽和数据传输速率方面存在的问题。

The paper introduces a high precision IF signal data acquisition card based on the theory of software radio. Compared with the traditional data acquisition card, presents a design scheme of the new-type data acquisition card. The experiment indicates that the new data acquisition card provides a good solution to the problems of signal process bandwidth and data transmission rate.
