Powell-Chau线性相位IIR滤波器的改进
An improved Powell-Chau linear phase IIR filter
摘要
Abstract
Aiming at the truncated noise of the Powell-Chau linear phase infinite impulse response (IIR)filter,the molecular polynomial of forward and backward filter was rearranged to decrease the Gibbs effect,and the correction filter was added to eliminate the noise.The results show that Gibbs effect and the truncated noise are eliminated effectively with the proposed method.关键词
