Abstract

A four diode (D1-D4) bridge (16) has four points of connection, a first terminal (C) comprising the transducer connection terminal and the opposite terminal (D) comprising a connection terminal for a transmission signal generator, the other two terminals being connected to means (18, 20) for biasing the diodes to make them alternatively conducting and blocking. A first switch (22) connects the first terminal of the bridge to the receiver terminal (12). A second switch (24) has one terminal connected to the receiver terminal (12) and the other connected to earth. Control of the biassing means and the switches is achieved by a superchronising unit.
