Abstract

This paper will show results relating to the sensitivity of Cauer, Chebyshev and Butterworth filters, obtained using LWDF (Lattice Wave Digital Filter) structures. These results have been obtained, uniquely, through sensitivity simulation programmes and LWDF filter designs. A comparative study will also be made, using sensitivity graphs, of the approximation rate used in the design, the frequencies zone and the study in broad bandwidth of this type of filter. Lastly, we shall draw our final conclusions from the analysis of the multiparametric sensitivity graphs obtained through the simulation programme `SEN CEL´
