摘要
文章根据介质膜滤波器为最小相位滤波器的特点,提出了一种从介质膜滤波器的幅度响应重构出相位响应,然后求出它的群速度延迟以及色散的数值方法.最后,实验验证了理论计算结果.
Based on the fact that dielectric film filter is minimum phase filter, this paper provided a method to reconstruct phase response from its amplitude response and then for the group velocity delay (GVD) and the chromatic dispersion. At last, the theoretical analysis was proven by experiment.
