| Abstract: | Based on summarizing the main design process of the frequency sampling method design,the scope of designing the special parameter and illuminating the relationship between the designing number of sampling value of transition zone and attenuation calculation of objective stop-band,a simulation design of a FIR filter by MATLAB is invesgated.The relevant data are listed and compared.Simulation results show that using frequency sampling method in FIR filter design,the maximum value of minimum stop-band attenuation,in condition that the number of frequency sampling points and the transition zone sampling points is chosen,will be obtained by selecting the appropriate sampling value of transition zone sampling points. |
