Özet

In this study, a method based on the Vortex Search algorithm is proposed for analog filter group delay optimization. To measure the performance of the proposed method, a number of all-pass filters are first cascaded to a fifth order Chebyshev low-pass filter and then the optimum parameters of these all-pass filters are searched by using the Vortex Search algorithm. It is shown that, the group delay of the fifth order Chebyshev low-pass filter (2.593s) can be decreased down to 1.547s by using an optimum fourth order all-pass filter.
