Thank you for reply @Mohamed Actually I am trying to implement microwave photonic filter the results attached on paper are in normalized format (attached in red colour according to selected wavelength). however the filter notch in mine simulation have at same place as stated in paper but with varriations. So as a beginner I am trying to overcome the mentioned problem.
1 more thing, is it possible to generate impulse in order to check response of microwave photonic filter? or another way is available to find the filter response.
Regards
