An emission–reception system that consists of two identical piezoelectric crystal plates is considered. The emitter is excited by a half-cycle of harmonic electric voltage at the eigenfrequency. Formulas have been derived for the emission mode and for the use of compensating electric pulses for the emitter and the receiver. On the basis of these formulas, calculations have been made and counterpart graphs have been provided in order to show, as an example, that electric pulses that are four and five half-cycles long can be generated at the output of the receiver.
