On the programming of cubic acoustic resonator with periodic time-dependent coefficient
Résumé
In this article, we investigate an electroacoustic resonator with a programmed cubic nonlinearity with constant and time-dependent coefficients. We design an experiment coupling an acoustic mode of a tube with a digitally programmable nonlinear resonator. Both simulations and experiments are carried out to compare optimized points for the resonator with programmed cubic nonlinearity with constant and time-dependent coefficients. We show that the frequency bandwidth of efficiency and the noise reduction are greater with varying nonlinearity than with constant nonlinearity.
