Hello, What are the methods used to obtain the Butterworth and Chebyshev filters of temporal filter box?
Regards

Re: Method used in the temporal filter box
Hello
The computation of the coefficients of these filters is implemented in openvibe/contrib/plugins/processing/signal-processing/src/algorithms/ovpCComputeTemporalFilterCoefficients.cpp
Best regards

Re: Method used in the temporal filter box
Hi,
are there any explanations for those functions/methods used in the temporal filter calculation?

Re: Method used in the temporal filter box
Hi,
the temporal filter box and the coefficient computations are components contributed by Guillaume Gibert at INSERM/U821 very very long time ago (before my time, at least 5+ years). There are some comments in the code and I presume that with some signal processing knowledge related to filter construction it would be relatively easily to spot the used approaches. Unfortunately however we don't have more documentation about it than the small box documentation and the code itself. If you can catch the original author he might remember the materials he used.
For convenience, here are the links to the implementation,

If you find out any answers, we'd appericiate sharing with the forum!
