查询词典 data acquisition

It consists of same three sets of acquisitive circuits,which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition,abandons vast of the redundant useless data at the same time,it only sends the useful data to the host computer by the way of DMA,so it is easy to processing the data.The design is concise and reliable.

但这本身也是一对矛盾，因为随着采集速度的提高，单位时间内采集的信号数据也就越多，而一般的采集卡在采集一定数量的数据后，总的需要一定的时间向主机内存传送数据，而在这段时间内是不能采集数据的，作为随机信号，如果在此时间内到来，则会造成信号的丢失。
