I have lists of measured data
where the samplepoints are not (!) distributed equidistant.
I want to apply an analog lowpass filter (1. order RC lowpass) to this list
to get a list of the filtered signal. I have the Signals&Systems package,
but the filters need to be applied to a function. So I turned these lists
into InterpolationFunction objects, but they don't work together with the
Signals&Systems toolbox. I tried to convert these InterpolationFunctions
objects into the PiecewiseContinuousData objects, but this didn't work
either with the filters.
Is there a way to use the Signals&Systems toolbox on such lists?
