Abstract
The output from the sensors is very weak in the strain testing system, interference signal is easily led into by sen-sors and long link wires, and interference is varied in different application conditions. A kind of IIR filter based on FPGA is de-scribed in this paper. Two order basic section as the core of the filter, its coefficient can change filtering model and cut-off fre-quency of the filter. LPF, HPF, BPF and BSF can be formed by writing the various coefficient to the filter by the embedded com-puter. This filter is applied in strain testing system, and get a good filtering effect.关键词
