用于电网谐波分析的抗混叠滤波器设计

Design of the anti - alias filter for the electric network harmonics analysis

根据电网谐波测试中信号分析的需要，介绍了用于电网谐波分析的抗混叠滤波器的设计原则和方法，给出了一种实用的抗混叠滤波器的设计，旨在缩小谐波分析仪的体积，降低功耗。

According to the needs of the electric network harmonics analysis, this paper introduces someprinciples and methods of designing the anti - alias filter for harmonics analysis, and gives a realistic designexample, in order to explain how to decrease the filter's volume and power loss.
