• Filter Signals a First Step in Interpreting Experimental Results 

      Leopa, Adrian (Universitatea "Dunăread de Jos" din Galați, 2010)
      After recording and storage of experimental data, a first step in their processing is filtering, ie, removal of parasitic components (noise) accompanying the signal due from other machines or equipment in service or ...
    • Study on the influence of Sonic Generator Geometry on Acoustic Parameters 

      Ștefan, Anca; Leopa, Adrian (Universitatea "Dunărea de Jos" din Galați, 2010)
      The acoustical parameters, dimensional determination and construction of sonic generator is described in the paper. The generator’s dimensional determination and construction show that the nozzle slot, the axial resonator ...
