A Fast Computer Aided Design Method for Filters

Gang Li


This paper presents a fast computer aided design method for filters based on model correction technique. Through the simulation of the submodels, the fitting formulas between the structure sizes and the coefficients can be determined. By pre-approved fitting formulas, the iterative correction is carried out on the filter structure sizes until the performance meets the specification. A design example is provided to explain the whole procedures. Simulation results agree well with the theoretical synthesis results which confirm the validity of the proposed method.
