Cycling noise filtering



I would like help trying to filter a signal in my data.


Data studied is 'ecart real', if you zoom on a small area (using Diadem or other), you can see a cyclic signal of about 75 pulses period.


I would like to filter that big oscillation and keep the small variation.


thank you!

You could pass this data through a software-based bandstop filter to remove the 75Hz noise. In an ideal case, you have to figure out what causes this noise and remove it at the hardware level.

Thank you.

Look like a relative displacement from the mechanical assembly. (This signal is a displacement)

Further investigation is necessary.


Could you refer some software? Hope to solve this displacement from the source too.


Thank you.
