NAŠE MORE : znanstveni časopis za more i pomorstvo, 2010 The subject of this paper is matching electrical hydroacoustic piezoelectric transducers, by means of an electrical transformer and a LC transformer, to the wave resistance of an antenna electric cable, which is connected to transceiver sonar. By using the ideal transformer model and LC transformer, special formulas were gained, which enables the ...
