Bandstop Filter Circuit Design and Parameter Optimization Based on Matlab

Various filter circuits often arise in analog circuit design.As the values of resistors and capacitors are not continuous in actual projects,the calculation of circuit parameters would be trivial and computationally intensive in designing the circuit.In addition,hand-calculation result would not be an optimal solution.This paper,by means of the powerful computation capacity of MATLAB,establishes a corresponding standard circuit model and parameter optimization model according to the transfer function of the band-stop filter,and finally circuit parameters which meet the requirements can be quickly obtained using the mathematical toolbox of MATLAB to program the corresponding solver,which greatly improves the design efficiency and is of great applicability.
