Design and Implementation of Digital Filter(DF) Based on FPGA
QI Hai-bing, Xiongfei Liu · Modern Electronics Technique · 2006
A design scheme which is using Altera DSP Builder to realize digital filter is proposed.Using a 16 order low pass FIR digital filter and state machine controlled sample signal as input signall.According to.bsf toplevel circuit,the filter software and hardware simulation of NCEDA2000C are realized.Results prove that the circuit is simple,credible and suitable for the design.
