The Design And Realization of Programmable Filter Based on FPGA
Zhao Yue · Microcomputer Information · 2010
A kind of designing schem for the filter controlled by Field-Programmable Gate Array (FPGA) would be proposed in this paper. The given filter could be composed by 3 modules : a prime amplifier , a filter and the controlling circuit based on FPGA. On the basis of digital controlling, The function for the parameter setting and displaying of the cut-off frequency to low and high pass filter would be realized. Because of the FPGA, the strong anti-interference ability and Reliability would be owned by the given-con- trolled programmer. The testing results illustrated that the design would be satisfied.
