How can I choose right filter based on unfiltered and filtered signals

Hi Matlabers
I have two signals in matlab. One is unfiltered and other is filtered. Second is just noiseless version of first unfiltered signal.
How can I find out which filter should I use to get that unfiltred signal from filtred one ?

You can't tell definitively. There are lots of different filters that could give the same output of a given signal. It could be a linear filter (like a low pass filter in the time/spatial or Fourier/frequency domain, or an inverse/Wiener filter), or a non-linear filter (like a median filter or whatever).
