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
