Signal acquisition is the necessary means of measurement and analysis . Currently on the market signal acquisition has many card types and different functions, mainly divided into high-speed signal acquisition card and low-frequency signal acquisition card, targeted for the majority of the design and few channels, limited scope. Therefore, this article and has designed a 32-channel analog signal acquisition card, use CPLD to achieve access control and acquisition AD conversion, the switch can access through the acquisition of 32 real-time signals, suitable for large-scale signal acquisition applications.
