I have measured the output of a mechanical system and obtained the signal shown at the attached image. I want to make it smoother by removing the chattering (I think it is called chattering). In order to achieve this I used a filter with transfer function:
$\ T(s) = \frac{30}{s+30} $
I used this filter to filter the measured data and the result was the the signal at the attached image. I would like to further process the signal to make it as better as possible. Can I achieve what I want by using another type of filter or is there any other process to follow ?
