In order to compare the composite and plain ceramics ultrasonic transducers the transmitting-receiving transfer functions and reflected pulses were calculated using Mason's equivalent circuit The transducer back-loading and the acoustical quarter wave matching to medium were taken into account. The results of calculation were confirmed by the experimental measurements.
