Abstract—Introduced a practical reconfigurable FIR filter system. According to the filter specialties, the filter coefficients are calculated by the computer. And the configured coefficients of the multistage FIR filter are downloaded to the chip. The filtering computing is completed by the FPGA. All these make virtual value of voltage and current more accurate and steady, so reseach on FIR filter Algorithms is the emphases and difficulty. The performance testing and application examples are given to verify this system.

Index Terms—finite impulse response digital filter, reconfigurable coefficient, Data-sampling
