### Purpose

Calculate the time derivation of a signal

### Description

"Derive" computes the time derivative of
the given signal with respect to the x-axis scaling. Internally, an
antisymmetric FIR filter is used to
perform the discrete differentiation.

Parameter:

- differentiation step d (as number of samples),

which is the length of the FIR filter (one-sided excluding zero)
used for the estimation of the local differential quotient.

### Macro Synopsis
