The results of a series of measurements characteris ing the amplifiers are presented. The measured amplitude and phase characteristics as a function of frequency for four selected amplifiers are analysed. The spectra of the output signal in the band from 4 kHz to 30 kHz are presented. The usefulness of the selected amplifiers in an underwater communication system is assessed.}, title={Suitability of acoustic power amplifiers as power amplifiers in underwater communication systems}, type={Article}, URL={http://journals.pan.pl/Content/133207/PDF/7-4762-A.Schmidt-sk-new.pdf}, doi={10.24425/ijet.2024.152067}, keywords={power amplifier, transmitter, underwater communications, amplitude, phase, spectrum}, }
