Numerical solution and verification of zero-pole for some fractal fractance approximation circuits
摘要
Abstract
With the development of the theory of fractance approximation circuits,one of the hot topics is how to solve the zero-pole of the circuits.The precise solution cannot be obtained by companion matrix.To solve the problem,based on the iterative circuit and iterative matrix,numerical solution of normalized zero-pole of fractance approximation circuit is achieved by two functions,"solve" and "roots",in Matrix Laboratory(MATLAB).The accuracy and speed of these two operations are compared.Then the zero-pole is verified by direct ways and indirect ways.The simulation results indicate that the accurate solution is obtained.The solution of zero-pole shows a guiding significance on analyzing the fractance approximation circuits.关键词
