View Full Version : Resampling data at different sampling rates

Dear all,

Talking of marriage (of data sets), I'm sure many of you out there have
come across situations where two data sets need to be married but have
different sampling rates. For example, kinematics could be recorded at
60 Hz whereas force sampled at 500 Hz. This is especially tricky when
the sampling rates are not easdily divisible. I guess you could do it
with some sort of spline such as Herman Woltring's GCV, but I once tried
the old FORTRAN routines, and while they did work, it would be nice to
find a better solution.

So, if somebody out there has come up with a nice solution to resample
the faster-sampled data (i.e. force) to the slower one (i.e.
kinematics), I would be grateful if you would share it with the rest of
