摘　　要：工频信号采集与处理在电力、通讯等诸多领域有着广泛的应用。文中详细论述了基于频率抽样滤波算法的工频信号采集处理方法,并提出了多频率抽样滤波方法,用以克服传统采集处理方法通带线性度差、带外衰减不理想、运算速度慢等缺点。在实际应用系统设计中证实该方法可靠有效、易于实现,特别适合单片机中工频采样数据的处理。Abstract Power frequency signal sampling and processing has wide applications in electric power and communication. This paper discusses the power frequency signal sampling and processing methods based on the arithmetic of sampling and filtering frequency. The method of sampling and filtering multiply frequency is introduced to overcome the disadvantages of poor linearity, attenuation out of band and low computing speed in conventional sampling and processing. In real practice and system design, the method proves reliable, and easy in realization.
