Abstract:This paper introduces and designs a Vibration Signal Acquisition System that it is able to achieve adaptive gain control. This system uses digital signal processor (DSP) and embedded processor (ARM).The feature of this system is that it can automatically adjust the gain of amplifier, which makes the system has a wider adaptability. Besides, it uses SPI interface for communications and data transmission between the DSP and ARM, which achieves high-speed vibration data acquisition.
