/*! \class GETFilterLowN2
 *
 *  This class defines a low pass filter of order N, based on 2 filters
 *  of order N/2 (see GETFilterLowN), one with positive cut frequency
 *  and the other with negative cut frequency, so that it does not
 *  introduce a shift of the signal.
 *
 *  The quality factor for sub filters (if any) is set automatically.
