| Abstract: | The characteristics of high speed maglev train's gap signal were analyzed,and a FIR digital filter was designed for it based on FPGA.A 16-order low pass FIR filer is implemented with distributed arithmetic based on multiple look-up tables and programmed by verilog-HDL.The method is also validated by simulation experiment on the bench of Simulink and ModelSim ISE 6.1. |
