Double Differentiation

The Double Differentiation is the operation that differentiates a signal twice consecutively according to time.

Note: As the primary application of this method is to convert displacement data into acceleration, the method which is implemented contains several steps that are specifically designed to avoid or limit unwanted effects generated by the integration step itself.

The processing steps applied to the signal when using Double Differentiation are as follows:

Double Differentiation simply applies the method used for Differentiation twice in succession.
