Take the derivative of a continuous time-series input wrt. time
0 = disable; 1 = first derivative; 2 = second derivative; etc
Base at which to unwrap numerical deltas. 2*pi ( = 6.283185307179586232) is a useful base to take in order to unwrap phase differences (when unwrapped at 2*pi, the first derivative of HilbertFilter output when OutputSignal=2 yields instantaneous frequency * 2 * pi).
Select whether to return raw sample-to-sample numerical deltas in seconds, or to divide these by the time delta to approximate a true derivative.
