Design of filter circuits for impedance matching of wideband transducers ABSTRACT Wide band piezo-composite transducer is a next generation transducer for under water application. The impedance matching on the interface between electro-acoustical transducer and electrical transmitter has been the most important subject to confirm the high transmitting efficiency. Because the impedance of a wide band transducer depends on signal frequency‚ it is difficult to design a matching network
