摘要：

In the general case, the problem of the wide-band matching of a piezoelectric transducer and an amplifier with an arbitrary active resistance is formulated. The results of investigation make it possible positively to solve. this problem under certain constraints on electrophysical parameters of the piezoelectric transducer. The general algorithm of solving the practical matching problem is carried out starting from measurements of the corresponding electrophysical parameters of the piezoelectric transducer. The limiting value of the extension coefficient is found using the Chebyshev filter for the equivalent RC-circuit of the piezoelectric transducer.
