An emitter in the form of a piezoelectric plate loaded on an aqueous medium is considered. Composite waveforms consisting of two half-periods are considered as electric signals fed to the plate, with one half-period exciting and the other one compensating. The pulsed transducer output signal is studied by D’Alambert’s method (without allowance for direct piezoelectric effect) and the Fourier spectral method. The similarity of the results indicates the correctness of applying d’Alambert’s method and the possibility for using it to assess the shape of signals emitted by the piezotransducer.
