| 摘 要： | 针对在ω=0和π处最为平坦的线性相位FIR槽状滤波器,利用Bernstein多项式推导出了计算其系数的显式。在给定槽口频率和带宽的滤波器的设计中,该方法不仅可行而且简单。经过实验测量,该槽状滤波器的频率响应与理想的频率响应非常接近。

| Abstract: | In this paper, Bernstein polynomials are used to derive an explicit formuIa for the coefficients of linear phase FIR notch filters which are maximally flat at ω=0 and π. The approach is relatively simple and can be used to design the filters with specific notch frequency and bandwidth. The frequency response of the FIR notch filter presented in this paper is very close to its ideal frequency response. |
