Possibilities for reducing the duration of acoustic pulses generated by a piezoelectric plate using a damper or an electric RL circuit for a plate excited by electric pulses of different durations

Calculation formulas were obtained for determining the shape of an acoustic pulse radiated by a piezoelectric plate that has a mechanical damper and a correcting electric circuit and is excited by electric pulses with durations that are multiples of an integer number of half periods at the antiresonance frequency ω 0 . Calculations were performed for particular cases when either an electric circuit or a damper is present. The optimal parameters of the electric circuit that provide the shortest duration of radiated signals were determined. The durations and amplitudes of radiated signals obtained using the damper or the electric circuit were compared. Conclusions concerning the degree of efficiency of applying an electric RL load were made.
