Abstract
Methods and apparatus are disclosed for substantially reducing the effect of the inherent transducer capacitance in a transducer-coupled electromechanical system which is subject to vibrational movement. First and second electromechanical transducers, mechanically coupled to the mechanical structure are interconnected by an electronic feedback network. The feedback network is characterized by very low input and output impedances thus overcoming the shunting effects of the inherent transducer capacitance. In preferred embodiments the feedback network is 'electronically cooled' thereby providing low-noise damping.
