摘要：
A method to determine the filter order and the locations of transmission zeros of self-equalized bandpass filters is presented, according to given filter specifications by optimization. The objective error function for the optimization is computed from the given filter amplitude and group delay specifications. The least filter order and the optimum locations of transmission zeros can be obtained to meet the required specifications by minimizing the error function using a genetic algorithm (GA). Application examples illustrate the excellent performance and the validity of this method.
