摘要：

We consider the results of the calculation of the frequency characteristics obtained in the solution of synthesis and analysis problems for reinforced rod piezo transducers containing two sections, which are generated by electric voltages different in both amplitudes and phases. A possibility is obtained to widen the passband up to two-three octaves by means of selecting the latter under the condition of providing characteristics of a uniform amplitude-frequency linear phase frequency of emission. We analyze the influence of generation methods and construction parameters of piezo transducers on these characteristics. The results of experimental investigations are presented.
