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.
