This analysis examines the mechanical bandwidth of a particular transducer structure and gives a way to deduce the electrical bandwidth of the whole system from the electrical components of the circuit and the mechanical bandwidth. An example is given for a cadmium-sulphide transducer on sapphire with a gold intermediate electrode.
