摘要	When Fiber-Optic Current Sensor(FOCS) measures the grid's small current, FOCS's output contains large noise due to the environment and components' inherent noise, which results in lower accuracy. In order to improve the small current's accuracy, a system of signal processing base on FIR real-time filtering was adopted. This text introduced the window functions' features and filtering system aiming at the FOCS's output was proposed. This system can adjust filter coefficient conveniently according to the output's character. By the AC experiment under room temperature, the result proves that the SNR of FOCS's output signal is improved by filtering and the current error ratio meets 0.2s class.
