How does one get data out of a TemporalData object?

I would like to generate some random signals for use in exploring signalprocessing algorithms.
For use as synthetic signals for the algorithm to chew upon, I'd like to use ContinuousMarkovProcess and TelegraphProcess with RandomFunction. With these, I can do statistics and plot things freely.
What I cannot quite get is a time series ready for such indignities as Fourier[].
Now I can manually disassemble the data structure, but I don't find a list of equispaced samples, I get a transition list, which is not the same thing.
Interpolation[Normal[temporal data object] // First, InterpolationOrder > 0] almost works, but the fine details are smeared over, even though InterpolationOrder > 0 works in ListLinePlot et al without apparent smearing.
What am I missing? It seems like Probability and Statistics has become a walled city within Mathematica. I'm hoping to find a door in the wall, rather than be forced to build by own little city one brick at a time.
