| Abstract: | General Chebyshev filter is a kind of high performance filter,whose parameters extraction with classic synthesis method is complicated and the topological structure formed by the method is unchangeable,this is inconvenient to use.In this paper,we show the clear physical meaning of each normalized circuit parameter by analyzing the equivalent circuit.Then based on the optimization method,we provide an effective and flexible method to extract the circuit parameters of general Chebyshev filter,when giving the position of the transmission zeros and the topology of the circuit.Finally MATLAB is utilized to implement the automatic extraction of equivalent circuit parameters. |
