| Abstract: | Hardware implemention technique of FIR filters is analyzed. Combining with the configuired Altera Corporation's FLEX10K series chip, the scheme of FIR filter hardware circuit is advanced and 8-tap FIR filter is designed, including AHDL to fulfill FIR filter and generalizing 16-tap and32-tap FIR filters. The circuit system design based on FPGA and its experimental results show that the system with FPGA is more reasonable and reliable and fulfill design requirement. |
