Detailed Description

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.

Constructor.

Parameters

n	sampling size of the channels

for use within ROOT.

GETFilterLowN2::GObject ( GETFilterLowN2  )

private

Macro from GCpp library that defines the following functions:

• ClassName(): return the real class name of the object
• StaticClassName(): return the used class name of the object (that may be a base class of the real object).
• IsInstanceOf<T>(): return true if the current object is an instance of the template class name argument
• Clone(): return an allocated copy of the object.

void GETFilterLowN2::UpdateFilter ( )

virtual

Compute the filter sample.

Reimplemented from GETFilterLowN.
