摘要
介绍采用硬件电路将测量信号分段输送给八位A/D,通过软件判别有效通道,然后进行数据处理,以提高八位A/D的转换精度,详细介绍电路设计。
To enhance the converting accuracy of 8-bit A/D converter, the author introduces a method, by which the measuring system signal is forwarded to 8-bit A/D in sections by hardware circuit and the data is processed by software through discriminating active channel. The circuit design is introduced in detail.
