Hi Jamiva

 

Thank you for your advice, I actually played around this function but I actually found the IIR filter more fitting in my case, The Topology - Inverse Chebyshev in 3 order looks like it will remove the fringes the best while comparing to other methods (See InvCheb.png).

 

However, I do not know how to tune the delay problem for this type of filter (See DelayProblem.png, where Green is original data, white is the Filtered data, ignore red which is a Gaussian vi, does anyone know how to align it with my sample data?

 

Again, I couldnt thank you enough for the guidance, guys!
