Description   This part describes the architecture BHV_RF of the lowpass filter.
It uses the package FILTER to compute the filter coefficients.
Filters of grade 1 to 6 are available. They are implemented using
the 'DOT attribute. A simpler implementation would use the
LTF statement.
ATTENTION: we observed problems with version 4.0_3.1 of ADMS
when using the doubled 'DOT'DOT attribute as in
this model
