| Abstract: | AC amplifier data acquisition board based on PCI bus is introduced in this article.Some circuits are integrated in the board,such as sensor power driver,preamplifier,modulation and demodulation,A/D conversion,decoding and serial parallel data conversion,PCI interface,and so on.Using the board,the strain load and the signals output by extensometer and differential transformer can be acquired directly to the computer for data processing.Then,the functions of the A/D card are expanded. |
