摘要
A/D转换器的分辨率决定着数据采集电路的量化精度。当某种因素限制了A/D转换器分辨率进一步提高时,通过对信号调理电路的合理设计,可以在原有的基础上使数据采集电路的分辨率提高一位。这可以使整个数据采集系统的性能得到进一步的提高。
The quantization precision of data acquisition circuit is determined by the A/D's resolution.When improving A/D's resolution is limited by same elements,the reso-lution of data acquisition circuit can be upgraded by designing the signal preamplifier circuit in advanced method.The performance of data acquisition system can be im-proved by this way.
