Abstract

As the equipment based on Embedded Systems always runs into the interference of 50Hz frequency signal, we usually adopt digital filters to filter 50Hz frequency signal and reserve useful signals. But in order to meet the requirements for real-time processing, we hope the transfer function of the filter will be as simple as possible and the coefficient is integer. This article discusses the design methods of integer coefficients comb filter and gives out two integer coefficients comb filters which meet the requirements for real-time processing.
