摘要

本文采用波形数字结构设计了互补陷峰滤波器，并利用Xilinx System Generator for DSP EDA工具在FPGA上实现。利用现有的全通滤波器设计理论，利用二阶谐振电路的波数字等效实现二阶全通功能。波形数字适配器系数可以直接调节滤波器的频率和带宽。

Notch/Peak filter Design and its FPGA Implementation through Wave Digital Structure

In this paper, complimentary notch/peak filter is designed using wave digital structure and then implemented on FPGA using Xilinx System Generator for DSP EDA tool. The existing theory of all-pass filter based design is used to realize second order all-pass function using wave digital equivalent of second order resonance circuit. It is also shown that the wave digital adaptor coefficients can directly tune the frequency and bandwidth of the filter.
