Zitat:This VI uses the 2nd Order Central method to calculate the differentiation. Let y represent the output dx/dt. y is given by the following equations:

y0 = (x0 – initial condition)/2dt

y1 = (x1 – initial condition)/2dt

yj = (xj+1 – xj–1) / 2dt, for j = 2, 3, 4, …

where yj is the output dx/dt of the (j+1)th call of this VI and xj is the input x of the (j+1)th call of this VI.

Edit: Ich habe es dennoch mal angeschloßen und bekomme exakt dieselben Werte geliefert, wie zuvor mit meiner Methode.
