Abstract :
Investigating and designing the A/D sampling circuit, at the same time designing the data transfer circuit based on the AT89C5131 USB interface. Firstly converting the analog signals into the digital signals by the A/D sampling circuit, and then transforming the digital signals to AT89C5131 MUC. AT89C5131 MUC transfer data to computer by USB interface, and then processing data by computer. Result of tested indicate that the original signal resumed by sampling system has little distortion, and all kinds of targets are according with the anticipation.
