1. The function of the «Actual resonator filter» is to outline the carrier frequency from the signal (the carrier frequency contains the useful signal). We use this filter to control operation of algorithms used for resonance and decrement calculation. You can set any frequency and decrement parameters with any precision values — what is more important is the precision of the results obtained.
2. Is better to use the «damping decrement» component from the «Seismic impact control system» clause — it has higher precision and «ThresholdCoefficient» parameter, which, in its turn, allows to separate the useful spectrum part from the noise level. More information concerning the damping decrement is available by the link — https://en.wikipedia.org/wiki/Logarithmic_decrement
3. It is difficult to say what is wrong with the project in remote way — probably the problem is in some minor detail.
4. You are right, the «Diagram» component does not allow to change the value of «Xprecision» parameter — we shall fix it soon.
5. TeamViewer program is available for downloading and installation from the official web-site. You should select the version for personal non-commercial use. Upon installation completion you will have to send me the 9-digit ID of your PC as well as the password for access.
