| Abstract: | In the traditional data acquisition system design,primary controller is hard to update and the transmission speed of transmission chip is low.This peper has designed a multi-channel data acquisition system based on FPGA and USB2.0.The system achieves acquiring 4-route data acquisition with the maximal frequency of 150 KHz and the precision of 12 bits.The system has desgined multi-channel FIR filter.This approach can achieve real-time filter and eliminate the interference.The system is modular design,high stability,can be widely used for multi-channel data acquisition. |
