The present work will present some results related to the implementation of a specifically designed digital FIR filters that, starting from results of “standard” numerical models (FEM/BEM or others), are able to reconstruct the time related system response and to digitalize the expected noise. First test have been performed on a geometrical simple box set-up, in relation to which both numerical model and experimental test campaign have been realized. The Matlab/Simulink implemented filters have showed good results in signal reconstruction opening to further application at more complex systems and real-time implementation.

Abstract
The present work will present some results related to the implementation of a specifically designed digital FIR filters that, starting from results of “standard” numerical models (FEM/BEM or others), are able to reconstruct the time related system response and to digitalize the expected noise. First test have been performed on a geometrical simple box set-up, in relation to which both numerical model and experimental test campaign have been realized. The Matlab/Simulink implemented filters have showed good results in signal reconstruction opening to further application at more complex systems and real-time implementation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
