<p><P>PROBLEM TO BE SOLVED: To maintain an optimum communication state under any conditions in a transceiver which induces an electric field in an electric field transmission medium on the basis of information to be transmitted and transmits and receives the information using the induced electric field. <P>SOLUTION: The amplitude of an electric signal outputted from a fixed gain amplifier 116 is measured by an amplitude measurement section 21. Connection modes of a receiver side connector 11 and a grounding side connector 13 are feedback-controlled by a controller 23 on the basis of a result of the measurement. Consequently, the strength of an electric signal to be outputted form a signal processing circuit 20 can be kept at a predetermined value, and the optimum communication state can be always maintained. <P>COPYRIGHT: (C)2004,JPO</p> |
