宽动态范围实时数据采集系统

A Real time Data Acquisition System with Wide Dynamic Range

介绍了一种新颖的数控增益自适应放大器，提高了Ａ／Ｄ转移器对小信号的分辨率和采集速度，克服了常规程控放大数据采集系统实时性和系统精度难以同时兼顾的缺陷。实现了宽动态范围输入信号的实时高精度数据采集。

Presents a novel gain adaptive amplifier based on digital control. It increases the resolution of A/D converter for weak signal, and enhances the velocity of data acquisition system, and gets rid of the weakness of real time and precision performance of data acquisition system based on normal programmable gain amplitier, and realizes real time and high precision data acquisition of input signal with wide dynamic range. Therefore, it is of great value to engineering measurement field or computer measuring control field.
