I guess that there is integration x(t) that can do the job.
However it is not causal since the integrated signal is obtained as y n =
f (x n-1, x n, x n+1 ) where x n is the singal to integrate.
Therefore, it is not reentrant like all IIR filters in Labview. I got a
Labview example making it practically reentrant for my app from
Jean-Claude Drolet last year. Thanks again Jean-Claude. It cam handy in my
vibration app.
Differentiation is a trickier business in practice since this increases HF
noise tremendously. I would suggest you make your own IIR filters to
introduce a time constant to get around this classical data processing
hurdle. Labview provides all tools to do that.
