Abstract
In a communication apparatus, an analog circuit includes a circuit element to be connected to a first conductor, and processes a differential signal. A communication circuit receives, via a connection circuit, a differential signal processed by the analog circuit, and generates a signal for which the potential of a second conductor is used as a reference potential based on the received differential signal. An inductor is connected between the first conductor and the second conductor. The connection circuit includes a circuit element different from a capacitor. The analog circuit (21), the connection circuit, the communication circuit, the inductor, the first conductor, and the second conductor are housed in a conductive housing box.
Claims8
A communication apparatus comprising:
- a first conductor and a second conductor;
- an analog circuit that includes a circuit element to be connected to the first conductor, and processes a differential signal represented by a voltage difference between two conductive wires;
- a connection circuit that includes a circuit element different from a capacitor, and is to be connected to the analog circuit;
- a communication circuit that receives, via the connection circuit, the differential signal processed by the analog circuit, and generates a signal for which a potential of the second conductor is used as a reference potential, based on the received differential signal;
- a connection element that is a circuit element different from a capacitor, and is to be connected between the first conductor and the second conductor;
- and
- a conductive housing box that houses the first conductor, the second conductor, the analog circuit, the connection circuit, the communication circuit, and the connection element,
- wherein the housing box is electrically connected to a conductor whose surface area is the larger of the first conductor and the second conductor.
