<p>The transducer circiut (200) comprises a transducer component (202), a drive circuit (210) for the transducer component (202), a control port (206) for coupling the drive circuit (210) to a control unit (102) and a modulator (222). The modulator (222) has an input port (236) for receiving a signal or data from another device. The modulator (222) has an output (232, 234) which is coupled to an output stage (216) in the drive circuit (210). The modulator (222) operates to transmit data, received at the input port (236), through the drive circuit (210) and the control port (206) to a control unit (102).</p> |
