摘要
介绍了一个基于80386微机的生理弱电信号采集系统,该系统具有预处理性能高、占用CPU时间少以及能够长时间连续采集数据等特点。
data acquisition system for weak physiologic electric signal is introduced, based on an80386 micro-computer. foe preprocessing unit has the characteristics of low-noise and high-CMRRdue to the elaborate technology.The CPU time of the system is exhausted only by one item, namelythe input of ADC data, because the MUX and ADC are controlled by the hardware. The system cancollect data in a continuous mode for a long time because of the expanded memory being employed insoftware design.
