Title:
COMMUNICATION DEVICE, SIGNAL SUPERIMPOSING CIRCUIT, AND SIGNAL SUPERIMPOSING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/027322
Kind Code:
A1
Abstract:
This communication device is equipped with: a first communication unit that transmits first information via a differential signal to a first wiring pair; a second communication unit that transmits second information via a differential signal to a second wiring pair; and a third communication unit that transmits third information by superimposing one part of a differential signal onto the first wiring pair and superimposing the other part of the differential signal onto the second wiring pair. Also, a signal superimposing circuit is provided with: a first superimposing circuit that applies a differential signal to the first wiring pair and superimposes one part of a different differential signal; and a second superimposing circuit that applies a differential signal to the second wiring pair and superimposes the other part of the different differential signal. By means of said configuration, it is possible to suppress unnecessary radiation.
