We present here a detailed analysis of the signal and noise response of a resonant gravitational-wave antenna in two cases:a) with the transducer mounted directly on the bar,b) with the transducer mounted on an auxiliary resonant mechanical oscillator which, in turn, is connected to the bar. The sensitivity, minimum detectable spectralenergy density of the gravitational radiation, is given in terms of the ratio between an effective temperature and the antenna mass. The effective temperature depends on the temperature of the bar, on the noise temperature of the transducer, on the matching among bar, transducer and preamplifier, and on the data analysis algorithm. We derive an expression for the optimum matching conditions which holds for both casesa) andb). When the matching conditions are fulfilled, the effective temperature becomes equal to twice the noise temperature of the amplifier, provided the Wiener-Kolmogoroff algorithm is used in the data analysis.
