Annotation
Thermal noise in a gravitational antenna with a piezoelectric transducer has been studied theoretically. The noise parameters of the piezoelectric transducer have been computed using the fluctuation dissipation theorem and standard techniques for describing noise in linear four-pole networks. The geometrical dimensions of the piezoelectric plate necessary to ensure low intensity of the excess noise for a reactive impedance of the source have been determined.
