Description
  • The main objective of this paper is the theoretical description of the suppression of the nonlinear attenuation and thus increasing of the quality factor of the given resonator. The decribed method is based on the active suppression of the second harmonic component of the sound. The resonator is driven by a piston whose motions is characterized by two superposed sinusoidal motions. The frequency of the first motion f is equal to the resonator eigenfrequency and the frequency of the second one is 2f and its the phase shift is 180 degrees.

  • Hlavním cílem této práce je teoretický popis potlačení nelineárního útlumu v akustickém rezonátoru, které vede ke zvýšení činitele jakosti tohoto rezonátoru. Rezonátor je buzen pístem, jehož kmity jsou dány složením dvou frekvencí. První je dána vlastní frekvencí rezonátoru, druhá je dvojnásobná s fázovým posuvem 180 stupňů. (cs)
