The device comprises a first input (E1) and a first output (S1) which are respectively capable of receiving and delivering a plurality of analogue signals and of corresponding digital signals having different predetermined types of transmission characteristics, and which are associated with substantially homothetic predetermined elementary attenuation frequency templates. A second input (2) and a second output (S2) are also provided, capable respectively of receiving and delivering a plurality of digital signals and of corresponding analogue signals having different predetermined types of transmission characteristics and associated with substantially homothetic different predetermined elementary attenuation frequency templates, as well as first and second signal conversion means arranged respectively between the first input and output and between the second input and output, and including a single digital filter (6) in common, having a single attenuation frequency template compatible with all the elementary templates. <IMAGE> |
