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