| Abstract: | This paper investigates a FPGA-based adaptive notch filter. Firstly, the LMS algorithm is analysis and the issue of stability in notch filter is introduced. Then, a way of implementing FPGA-based adptive notch filter is provided. Finally, an experimental platform is built to verify the notch filter. The simulation and experimental results show that the LMS algorithm has better effect. |
