摘　　要：针对基于DSP的电力参数测量装置中采用普通硬件实现低通滤波器存在的问题,提出采用Maxim公司的有源滤波芯片MAX 274设计抗混叠低通滤波器的方法,并给出实验数据。实践证明,该滤波器达到了实际应用要求,可以大幅度提高电力参数测量装置的实时性、精确性和稳定性。为电力参数测量装置中抗混叠低通滤波器的设计提供了有效的解决方法。Contraposing the problem of low - pass filter which adopts general hardware in the electric power parameter measuring device based on DSP, the method of designing anti - aliasing low - pass filter which adopts active filter MAX 274 of Maxim Company is introduced,the experimental data is given. Practices prove that this filter achieves factual application requirement and improves real- time quality,accuracy and stabilization of electric power parameter measuring device. An effective solution is provided for anti - aliasing low power filter in power parameter measuring device.
