| Abstract: | Adopt the DSP TMS320C55XX of TI Corporation to realize the IIR filter＇s design, to design the minimum order Chebyshev low-pass filter with the help of the FDATool, and to utilize Code Composer Studio （CCS） for debugging and simulation of the relative software and hardware. The results show that the filter can effectively filter out interfer signals and this design is simple and reliable, and simulation test indicates that the filter can operate stabely. |
