Hey ppal,

I am very sorry to say but its not possible for me to share the data as my system will not allow..

Please give some suggestion for how to proceed and what to do with this In_phase and Quadrature_phase.

Thank you

Hi

Make some data up. You don't have to give actual data. But you also have to attach your mathcad so the forum members can get an idea where you need assistance. Also note that this is not a python forum. But this may help
