System design of DSP control data collecting instrument

This text introduces the whole design process of data collecting system which is controlled DSP in detail.The system mainly adopt DSP’s controlled chip,collecting 16 bits number which is converted by 16 bits analog-to-digital controlled chip named AD976 and the 16 bits number accomplish communicating with last computer after processed by DSP.It has mainly been applied in such as the modern circuit design technology,sampled technology,filter technology,digital filter technology,DSP technology,digital signal processing and so on,which make the system to be a classical production of data collecting.
