transfer function

[e]

I'm rather new with using Labview.

Is there any way to put a signal through a transfer function in the
Laplace domain. Something like the block "transfer function" in
Matlab's simulink. I know the same thing can be approximated by
filtering the signal, intgrating it etc. but is there a simpler way?

Thanks in advance,

Erwin.

I think you mean:
.....\LABVIEW\vi.lib\Gmath\Trans.llb\Laplace Transform Real.vi
Only if you have the Gmath toolkit included in your LV package, but I think
that comes standard with new (5.0+) LV packages.
See also online reference on:
....\LABVIEW\VI.LIB\GMATH\trans.llb\Fractional FFT.vi

No, haven't got it, but i'll contact NI for an update.
My goal was to display the step response of a simple RC network (6
components). In the absence of the Tranfer function block, i've now
sent a stepped signal through gain, first order Bessel filters and
integrators, and added the outputs.

Thanks!
