    This passage design a signal acquisition circuit of digital high speed and full isolation. By using the V/F, F/V transformation to realize the transmission of analog signals, and using the infrared communication to realize the acquisition and processing board between class communications, using the high-speed A/D to realize implementation of the analog signal acquisition.
