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