Abstract
The circuit and the method serve to transmit a transmission signal to a transducer and to receive a reception signal from the transducer. The transmitter and the receiver are each alternatively coupled to the transducer and decoupled from one another. The coupling and decoupling is thereby achieved by a total of three nonlinear two-terminal networks (Z1, Z2, Z3). The transmitter is connected to the transducer via a bipolar voltage limiter and the receiver is connected to the transducer via a bipolar current limiter.
