The Study of Rejecting Harmonic Interference in Power Line Communication Using IIR Notch Filter Based on All-Pass Filter(APF) 基于全通滤波器(APF)的IIR陷波器在抑制电力线通信中的谐波干扰的研究
This paper presents a new frequency measurement which applied the all-pass filter of SAW to improve the low-frequency signal measurement accuracy. 传统的测频法对于低频信号的测量误差较大,本文提出了利用基于声表面波带通滤波器的一种新的测频法,提高了低频信号的测量精度。
For satisfying linear phase and amplitude frequency characteristics, we must add all-pass filter to revise phase. So it increases complexity and order of filter. 为了满足线性相位,通常要加全通滤波器(APF)进行相位校正,这同样增加了滤波器的阶数和复杂性。
