| 20100308851 | TESTING DEVICE AND METHOD FOR DETERMINING A COMMON MODE SIGNAL OF AN ELECTRICAL TELECOMMUNICATION - A testing device including: a first terminal configured to be connected to an equipment under test; a common-mode detector configured to detect a common-mode part of a signal emitted from the equipment under test; and a first impedance unit connected in series between the first terminal and the common-mode detector. The first impedance unit is configured to adjust a longitudinal conversion loss of the testing device to a predetermined value. A corresponding method determines a common mode signal of an electrical telecommunication. | 12-09-2010 |
| 20110206140 | DEVICE FOR DETERMINING A COMMON-MODE SIGNAL IN A POWER LINE COMMUNICATION NETWORK - A device for determining a common-mode signal in a power line communication network. The device includes a first line, a second line, and a third line that are connected to a first terminal, to a second terminal, and to a third terminal, respectively. The first, the second, and the third terminal are configured to be connected to a phase line, a neutral line, and a protective ground line of the power line communication network, respectively. The device further includes a common-mode choke configured to couple out the common signal from the first, second, and third line, and the common-mode choke is connected to a termination impedance which is higher than an impedance of the power line communication network. | 08-25-2011 |
